Embodiment Construction

[0022] The photosensitive drum and its transmission parts and the assembly method of the photosensitive drum of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Figure 1~4 , respectively show a perspective view and a cross-sectional view of the transmission part for the photosensitive drum of the present invention from different perspective angles. Figure 5 An assembly process of the photosensitive drum 100 is shown.

[0024] see Figure 1~4 , and combined with Figure 5 .

[0025] The photosensitive drum 100 is composed of a photosensitive member 200 and a transmission member 300 .

[0026] The photosensitive component 200 adopts a hollow cylinder made of aluminum material, that is, an aluminum cylinder 201 as a basic component. A photosensitive layer 202 made of photosensitive material is coated on the outer cylindrical surface of the aluminum cylinder 201 .

[0027] The transmission part 300 is a component...

Abstract

The invention relates to a photosensitive drum, a transmission component for the photosensitive drum, and an assembly method of the photosensitive drum. The transmission component comprises an engaging part connected with a photosensitive component of the photosensitive drum. The engaging part is a cylinder with an external cylindrical surface. The diameter of the external cylindrical surface is the same as that of the surface of an inner cavity of the photosensitive component. A groove extending towards the center of the cylinder is formed in the external cylindrical surface in the radial direction of the cylinder. One side, close to the center of the cylinder, of the groove in the radial direction of the cylinder is communicated with one side, back to the engaging part and the photosensitive component, of the transmission component by hollow pipelines. Ports, back to the engaging part and the photosensitive component, of the hollow pipelines are communicated with an atmospheric environment. The transmission component serves as one of members of the photosensitive drum. When the photosensitive drum is assembled, the engaging part is inserted into the inner cavity at one axial end of the photosensitive component, and then colloid is pressed into the groove via the hollow pipelines till the groove is fully filled with the colloid. The transmission component can be tightly and closely contacted with the photosensitive component due to the construction of the transmission component, and a photosensitive surface can be prevented from pollution when the photosensitive drum is assembled.

Description

technical field [0001] The invention relates to a photosensitive drum, a component part of a laser printer, a transmission part applied to the photosensitive drum, and an assembly method of the photosensitive drum. The photosensitive drum is composed of a photosensitive part and a transmission part. Background technique [0002] The working process of laser printers is usually that the outer cylindrical surface of the photosensitive drum is uniformly charged by the charging roller. The laser scanner emits a modulated laser beam containing image information to the photosensitive drum. After the laser is irradiated, an electrostatic voltage pattern with different distribution is formed on the outer cylindrical surface of the photosensitive drum, that is, an electrostatic latent image corresponding to the image to be copied. Afterwards, the toner from the developing roller is absorbed on the outer cylindrical surface of the photosensitive drum, covering the electrostatic laten...
