摘要： A process cartridge (100) includes a housing having walls (102,104,106) defining a process chamber (18) and a photoreceptor (84) mounted to the walls (102,104) within the process chamber (118) and having a closed loop path and an imaging area (210) having a given length (Li). The process cartridge (100) also includes plural process components acting along the closed loop path for producing imaging effects 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 (214) having an acting region precisely only as long as the length (Li) of the imaging area (210), 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 (92), for applying charged toner particles to the imaging area. The developer roll (92) has an acting region centered relative to, and extending slightly beyond, each end of the length (Li) of the imaging area (210). Importantly, the process components include a cleaning component that includes a cleaning blade (138) for removing waste toner from the imaging area (210), and an auger for transporting the waste toner in a waste toner flow direction (220). The cleaning blade (138) has an acting region slightly longer than the length (Li) of the imaging area (210), and that is offset relative to the imaging area in the direction of waste toner flow, thereby enabling the process cartridge (100) to reliably and effectively produce and transfer high quality toner images.
