Abstract

The invention discloses a drum frame, a developing box and a processing box, and belongs to the technical field of image forming equipment. A photosensitive drum, a developing box and a drum frame capable of containing the photosensitive drum and the developing box are provided. The drum frame comprises a containing cavity formed by a main body, side plates and a transverse plate and used for containing the developing box, the drum frame further comprises a first supporting unit and/or a second supporting unit, at least one side plate is provided with the first supporting unit, and the side plate and/or the transverse plate is provided with the second supporting unit; the developing box is provided with a first supported unit and/or a second supported unit, the first supported unit is used for being matched with the first supporting unit, and the second supported unit is used for being matched with the second supporting unit; when the developing box is installed in the drum frame, the first supporting unit abuts against the first supported part and/or the second supporting unit abuts against the second supported part. By adopting the technical scheme, the compatibility of the drum stand is improved.

Description

technical field [0001] The invention relates to the technical field of image forming equipment, in particular to a drum frame, a developing box and a processing box. Background technique [0002] The process box is the most important component in the printer. The process box includes a drum frame with a photosensitive element and a developing box positioned through the drum frame. The photosensitive element in the process box can convert image information into an electronic latent image, and then convert the electronic latent image Convert to a solid toner image and transfer the toner image to a print medium. As the printing operation continues, the toner loaded in the process cartridge is gradually consumed, that is, the process cartridge is a consumable item and needs to be replaced frequently. [0003] In addition, there are many styles and models of printers on the market, and OEM manufacturers often produce process cartridges with different structures according to diff...
