Embodiment Construction

[0024] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] 1. Image forming equipment

[0026] Such as figure 1 As shown, the image forming apparatus 1 includes a main body casing 2 . A cartridge attachment / detachment opening 3 and a front cover 4 that opens and closes the cartridge attachment / detachment opening 3 are formed on the side wall on the front side of the main body case 2 . Incidentally, a laser printer is an example of the image forming apparatus 1 .

[0027] Incidentally, the front side of the image forming apparatus 1 is the front side in the front-rear direction. Also, in a state where the image forming apparatus 1 is placed on a flat surface, the direction orthogonal to the flat surface is the up-down direction. Left and right of the image forming apparatus 1 are defined when the image forming apparatus 1 placed on a flat surface is viewed from the front side.

[0028] The process cartr...

Abstract

A photosensitive cartridge includes: a photosensitive member mounted to the photosensitive cartridge such that a surface thereof is movable in a first direction; an electric discharge electrode that extends in a second direction at an interval with the surface of the photosensitive member, the second direction being orthogonal to the first direction and is parallel with the surface of the photosensitive member; a frame holding the photosensitive member and the electric discharge electrode and including an opening at an opposite side of the photosensitive member across the electric discharge electrode, the opening extending in the second direction; a cleaner movable along the opening so as to clean the electric discharge electrode; and a reinforcement member, which is a separate member from the cleaner, and which is contactable the frame to reinforce a surrounding part of the opening.

Description

technical field [0001] The present invention relates to a photosensitive cartridge mountable in an image forming apparatus. Background technique [0002] In an image forming apparatus such as a laser printer or the like, a process cartridge is detachably mounted in a main body of the image forming apparatus. [0003] The frame of the process cartridge holds a photosensitive drum, a charger, and a developing device. When forming an image, the photosensitive drum rotates at a constant rotation speed. Accompanying this rotation, the surface of the photosensitive drum is uniformly charged by the charger. Then, the uniformly charged portions are selectively exposed, so that an electrostatic latent image is formed on the surface of the photosensitive drum. When the electrostatic latent image faces the developing device, toner is supplied from the developing device to the electrostatic latent image, so that the electrostatic latent image is developed into a toner image. The ton...
