摘要： A cleaning apparatus and a fixing apparatus include a cleaning web configured to remove toner adhering to a rotation member, the cleaning web including a recessed portion in at least a part thereof, and a displacement mechanism configured to situate a relative position between the rotation member and a pressure member configured to press the cleaning web toward the rotation member at a first position where the cleaning web is pressed toward the rotation member by the pressure member and at a second position where the rotation member and the pressure member are farther from each other than at the first position. The displacement mechanism situates the relative position at the second position based on an output of a detection position configured to detect a position of the recessed portion, so that a rear end of the recessed portion is not pressed toward the rotation member by the pressure member.

摘要： A process cartridge including a housing having walls defining a process chamber and a photoreceptor mounted to the walls within the process chamber and having a closed loop path and an imaging area having a given length. The process cartridge also includes plural process components acting along the closed loop path for producing imaging affects on the photoreceptor for forming on, and for transferring from, the photoreceptor, a toner image. The process components include a charging component that includes a pin-array charge emitting device having an acting region precisely only as long as the length of the imaging area, in order to avoid occurrence of "dark bands" towards edges of a formed and transferred toner image. The process components also include a developer roll for applying charged toner particles to the imaging area. The developer roll has an acting region centered relative to, and extending slightly beyond, each end of the length of the imaging area. Importantly, the process components include a cleaning component that includes a cleaning blade for removing waste toner from the imaging area and an auger for transporting the waste toner in a waste toner flow direction. The cleaning blade has an acting region slightly longer than the length of the imaging area, and that is offset relative to the imaging area in the direction of waste toner flow, thereby enabling the process cartridge to reliably and effectively produce and transfer high quality toner images.
