Abstract

The invention provides a processing box and a mounting method thereof, and an electrophotographic imaging device. The processing box includes a box body, a sensitometric drum and a development roller,wherein the sensitometric drum and the development roller are rotataby supported between a first end wall and a second end wall of the box body, an axial end of the sensitometric drum close to the first end wall is provided with a coupling protrusion, an axial end of the development roller close to the first end wall is provided with a development roller gear, in the axial direction of the sensitometric drum, the development roller gear is closer to the first end wall relative to the coupling protrusion, and the development roller gear and the development roller are coupled through an axial clutch in the axial direction of the development roller. The processing box is advantaged in that developer leakage can be prevented.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to an electrophotographic imaging device, a process box detachably installed in the electrophotographic imaging device, and a method for installing the process box. Background technique [0002] An existing process cartridge includes a photosensitive drum, a coupling protrusion positioned at the axial end of the photosensitive drum, a developing roller, and a developing roller gear positioned at the axial end of the developing roller. The minimum distance between them is greater than the minimum distance between the developing roller gear and the drive end end wall of the process cartridge. [0003] A drive head is arranged in the box chamber of the electrophotographic imaging device, and the drive head is engaged with the developing roller gear and the coupling protrusion at the same time by the rotational force. Since the driving head of the machine needs to drive the c...
