Problems solved by technology

However, because the modified guide mechanism of this general processing box cannot coincide with the drop-off slideway in the equipment, the processing box cannot be accurately positioned in the equipment, so that the position of the processing box changes during the imaging process, resulting in printed images. The image is whitish, and there are defects such as paper jams and abnormal noises in the electrophotographic imaging equipment

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Process cartridge embodiment

[0022] like figure 1 As shown, the process box includes two interconnected box bodies 1 and 2, a photosensitive drum 3, a cleaning blade 4, and a charging roller 5 are installed on the box body 1, and the box body 1 has a waste toner bin 6 for containing waste toner , The developing roller 7, the powder feeding roller 8, and the stirring frame 9 are installed on the box body 2, and the box body 2 has a powder bin 10 for accommodating carbon powder. When the process box is installed on the electrophotographic imaging device to work, the surface of the photosensitive drum 3 is charged by the charging roller 5. After exposure, the surface of the photosensitive drum 3 forms an electrostatic latent image. The powder roller 8 is conveyed to the developing roller 7, and the developing roller 7 develops the electrostatic latent image o...

Abstract

The invention aims to provide a processing box capable of accurately positioning electronic photographing imaging equipment and a method for accurately positioning the processing box. The processing box provided by the invention comprises a box body, wherein a powder bin containing carbon powder is arranged in the box body; the box body is provided with a pressed part; and the pressed part is located on the downstream side in the mounting direction of the processing box.

Description

technical field [0001] The present invention relates to a process cartridge used in an electrophotographic image forming apparatus and a method for accurately positioning the process cartridge. Background technique [0002] In electrophotographic imaging equipment, a process cartridge detachably installed inside it is usually used. The process cartridge contains a photosensitive drum and a developing device. After the photosensitive drum is selectively exposed, an electrostatic latent image is formed on its surface. Toner delivered by the device visualizes this electrostatic latent image as a toner image, which is then transferred onto a recording medium to form a visible image. [0003] With the development of electrophotographic imaging technology, electrophotographic imaging equipment is constantly being introduced, and the structure of the process box used in the series of electrophotographic imaging equipment is similar. At present, there are four types of electrophoto...
