Embodiment 1

[0015] As shown in Figures 1 and 2, the developing cartridge 3 includes a box body and a side end cover with a powder bin and a developing device, a developer stirring device located in the powder bin, a powder feeding roller for feeding the developer to the developing roller, The developing roller used to develop the electrostatic latent image on the photoreceptor is used to control the limit sheet behind the developer layer on the developing roller. The gear sets at each roller end outside the side end cover are provided with drive positions with power ports.

[0016] The special feature is that the shell of the box body in the direction perpendicular to the side end cover is arc-shaped, and the box body and the side end cover are connected into one body.

[0017] There may be two or more power ports.

[0018] For example, the double drive power receiving ports 41, 42 are located on the gear cover 6, and the gear cover 6 is connected to the right end cover 2 with screws 51, ...

Embodiment 2

[0020] In Embodiment 1, the right end cover 2 is connected to the powder bin by screws.

[0021] The left end cover of the developer box and the powder bin can also be connected in the same way.

[0022] Or, the left end cover, the right end cover and the powder bin of the developing cartridge can be connected in the same way simultaneously.

[0023] Alternatively, the connection mode between the end cover and the powder bin can be a lock pin or a lock.

Abstract

The invention relates to a developing device removable from an imaging device, especially a developing box, comprising: a box body containing powder storehouse and developing device and side end cover, a developer mixing device located in the powder storehouse, a powder supply roller to supply developer to developing roller, a developing roller to develop static latent image on photosensitive body, and a limiting piece to control thickness of developer layer on the developing roller, where there is a drive bay with power receiving mouths in each roller-end gear set outside the side end cover, and it is characterized in that: the casing of the box body in the direction vertical to the side end cover is of an arc shape, the box body is integrated with the side end cover; the number of side end covers is one or two; the box body and the side end cover are connected by lockpin, locker or bolt; the number of power receiving mouths is two or more; it saves manpower, material resources and financial resources, and besides, its appearance is more beautiful; its universality is improved.

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...
