Abstract

A photosensitive drum (101) for a laser printer comprises a photosensitive component (114) and a transmission component (115). The transmission component (115) is fixed on one side of the photosensitive component (114) along the lengthwise direction thereof. One end of the transmission component (115) along the length direction of the photosensitive component (114) that faces away from the photosensitive component (114) is provided with a cylindrical stressed block (117). An external end wall of the stressed block (117) along the axis direction thereof that faces away from the photosensitive component (114) is provided with a blind hole (121) recessed inwardly along the axis direction thereof. The blind hole (121) is provided with a continuous hole wall on an axial cross section of the stressed block (117). The number of blind holes (121) is four. On the axial cross section of the stressed block (117), four blind holes (121) are symmetrically distributed relative to the radial centre of the stressed block (117). The stressed block (117) of the photosensitive drum (101) and a driving head (119) of the laser printer are positioned to be aligned accurately, thus stably acquiring the required rotational driving force from the laser printer.

Description

technical field [0001] The present invention relates to a photosensitive drum as a component of a laser printer. The photosensitive drum is composed of a photosensitive part and a transmission part. 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 cylind...
