The present disclosure relates to a surface energy reduction material in the form of a topcoat or additive to a coating that may be applied to a toner regulating member such as a doctor blade which may reduce toner build-up about a nip region, pre-nip region, and/or post-nip region. The surface energy reduction material may be include any material having a surface energy of less than or equal to 35 dynes/cm, for example, between 15-30 dynes/cm, including all values and ranges therein. The surface energy reducing materials may include any material that provides a 25% or more reduction of the surface energy of the doctor blade compared to an untreated doctor blade, for example, greater than or equal to 50% reduction or greater than or equal to 75% reduction, including all values and ranges therein.

A doctor blade assembly () for an image forming device such as a laser printer () includes a bracket () to which foam () is attached providing improved tolerances in the nip formed between the assembly () and the doctoring media. The assembly () includes a lip () which extends under the foam () to help secure the foam () and reduce the amount of adhesive required to keep the foam () attached. The bracket () is stamped from a single piece of metal providing a doctor blade assembly () with high stiffness that is cost effective to manufacture.

An apparatus and method for the transport and/or storage of developing agent in an image forming apparatus. A cartridge may be employed having a reservoir for developing agent and a component, such as a drum, which may include an interior region capable of storing developing agent. A transport device may be included that is capable of transporting developing agent between the reservoir and a location in the image forming apparatus such as the drum interior.

A toner cartridge for an imaging apparatus having a housing including two opposed end walls and an elongated body therebetween and an exit port. An inner surface of the body defines a toner reservoir that is communication with the exit port. A drive shaft is rotatably mounted within the housing. A toner platform is provided in slidable contact with the inner surface of the body and is nonrotatable relative to the housing. A drive shaft coupling couples the toner platform to the drive shaft. An exit paddle is positioned adjacent the exit port and is rotatable by the drive shaft. Rotation of the drive shaft translates the toner platform toward the exit port and rotates the exit paddle. As the toner platform moves, toner within the reservoir moves toward the exit paddle and exit port and rotation of the exit paddle moves toner through the exit port.

A vent integral with the top surface of toner hopper () having three labyrinth channels () oriented in one direction and three labyrinth channels () oriented in an orthogonal direction. Each labyrinth communicates with the inside of the hopper by a hole () and the end of each labyrinth communicates with filter pad () held in a basin () formed in the top surface of hopper (). Cover () closes the vent except for hole () over the center of pad ().

A toner cartridge for an imaging device having a housing having a toner reservoir and an exit port in fluid communication with the toner reservoir. A drive shaft rotatably mounts within the toner reservoir. A toner platform is movably coupled to the drive shaft and is nonrotatable but slidable relative to the housing. A resilient arm is positioned within the reservoir and biased toward an initial position in the path of the toner platform. When the drive shaft rotates, the toner platform translates toward the exit port. When the toner platform contacts the resilient arm, the resilient arm moves to permit the toner platform to pass and when the toner platform moves further toward the exit port the resilient arm returns to the initial position. The resilient arm may mount on the inner surface, the toner to platform or the drive shaft.

A conveyor mechanism for moving waste toner within an interior of a waste toner reservoir. The conveyor mechanism has a first end positioned in proximity to an inlet into the waste toner reservoir, and a second end positioned vertically above the first end. The conveyor mechanism operates to move the toner from a lower position within the waste toner reservoir to the vertically elevated position. The conveyor device may allow for the capacity of the waste toner reservoir to be more fully utilized. In use, the conveyor device is activated and waste toner is moved into the upper reaches of the waste toner reservoir.

A toner release coating may be applied to a toner regulating member such as a doctor blade. The toner release coating may reduce toner adhesion at a doctoring pre-nip location of the doctor blade. The toner release coating may be formed from a mixture of lubricating particulate and polymeric binder resin in a liquid carrier.

A toner cartridge for use in a laser printer has a toner reservoir or hopper in which an agitator is pivoted by a rotating paddle away from its home position proximate an exit opening and then returned to its home position by a spring exerting a predetermined desired force on the agitator after the agitator ceases to be moved by the paddle. The spring may be a cantilever spring, a torsion spring, or a stamped and formed leaf spring.
