Description

technical field

[0001] The invention relates to a developing device detachable on an imaging device, in particular to a developing box. Background technique

[0002] In image forming devices such as laser printers, copiers, and all-in-one printers, an electrostatic latent image is formed on the surface of a photosensitive drum as an image carrier, and the electrostatic latent image on the photosensitive drum is transferred from the surface of the developer carrier as a developing device. The developer carried on the developing sleeve is developed to form a visible image. The developer image is transferred onto the material to be transferred, and the developer image is fixed and output on the transfer material by a fixing device. Chinese patent application 02102284.4 discloses an image processing unit that is detachably combined with a photosensitive unit and a developing unit. The photosensitive unit has at least one photosensitive drum and a transfer roller, and the develo...
