Process cartridge and image forming device

Abstract

The invention provides a processing box, an image forming device and a developing box. The processing box is detachably arranged on an image forming device main body. The processing box comprises thedeveloping box and a drum box, wherein a connecting piece is arranged on the developing box; the drum box comprises a drum box main body, an accommodating part, a locking device and an unlocking device; the accommodating part is arranged on the drum box main body; the accommodating part accommodates the connecting piece; the locking device can cooperate with the accommodating part to lock and position the connecting piece, so that the developing box and the drum box are relatively locked; and the unlocking device is used for being in contact with the image forming device main body in the process of mounting the developing box to the image forming device main body, and is subjected to an action force of the image forming device main body to drive the locking device to relieve locking and positioning of the connecting piece, so that the developing box can be separated from the drum box. The use convenience can be improved.

Description

technical field [0001] The invention relates to image forming equipment technology, in particular to a process box and an image forming device. Background technique [0002] Image forming devices, such as laser printers, copiers, compound machines and other products, are generally provided with a process box inside. [0003] Existing process cartridges generally include a drum cartridge for accommodating a photosensitive drum and a developing cartridge for accommodating developer. The connecting piece is located in the accommodating portion, and the locking device can cooperate with the accommodating portion to lock the connecting piece, so that the drum cartridge and the developing cartridge are relatively locked. [0004] In the prior art, when the process cartridge is installed in the image forming device, if the user wants to take out the developing cartridge separately, he needs to manually unlock the locking device for the connecting piece, so that the connecting piec...

Problems solved by technology

[0004] In the prior art, when the process cartridge is installed in the image forming device, if the user wants to take out the developing cartridge separately, he needs to manually unlock the locking device for the connecting piece so that the connecting piece can be separated from the accommodating part, and then Only then can the developer box be taken out separately, which is inconvenient to operate
