Abstract

A developing cartridge (200) for a laser printer comprises a stirring wheel (206) and an excitation mechanism. The excitation mechanism comprises a diameter changing wheel (208), a return spring (219) and a sliding block (218). The diameter changing wheel (208) has two sections of circular arcs (210, 211), and a larger-diameter circular arc (210) is meshed with the stirring wheel (206). A lug (214) is disposed on an end wall (213) at one side axially facing an end cover (207) of the diameter changing wheel (208). A position corresponding to the diameter changing wheel (208), of the end cover (207) is set to be an inclined wall (215). The inclined wall (215) is provided with a sliding groove (216). The sliding block (218) is disposed in the sliding groove (216). The return spring (219) presses against the sliding block (218) on one end close to the diameter changing wheel (208), of the sliding groove (216). An end head (225) close to the diameter changing wheel (208), of the sliding block (218) is located in front of the lug (214) making a circumferential motion, and extends to the root part of the lug (214).

Description

technical field [0001] The invention relates to the technical field of electrophotographic imaging, in particular to a developing box for a laser printer. Background technique [0002] The imaging process of the laser printer with the process box 100 as the basic core is, see figure 1 , the surface of the photosensitive drum 101 is uniformly charged by the charging roller 102 . The laser scanner 103 emits a modulated laser beam 104 containing image information to the outer cylindrical surface of the photosensitive drum 101, and after being irradiated by the laser beam 104, an electrostatic charge distribution map with differences in distribution is formed on the cylindrical surface of the photosensitive drum 101, also That is, the electrostatic latent image corresponding to the image to be reproduced. Afterwards, the developer such as carbon powder 106 transmitted from the developing roller 105 turns to be adsorbed on the cylindrical surface of the photosensitive drum 101 ...
