Developing box

Abstract

The invention relates to a developing box. The developing box comprises a shell and a driving assembly, wherein the driving assembly is arranged at a longitudinal tail end of the shell and comprises apower transfer device and a motion rod assembly, the power transfer device is arranged in the developing box, the motion rod assembly is combined with the power transfer device and comprises a firstmotion rod and a second motion rod, the first motion rod and the second motion rod are combined, the first motion rod is combined with the power transfer device, the second motion rod rotates in planes where a horizontal direction Y and a vertical direction Z of the developing box are located around a rotational axis L3 when the second motion rod receives an external force, and the first motion rod is driven to move in a direction which planes where a longitudinal direction X and the vertical direction Z of the developing box are located intersect by the second motion rod.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a developing box detachably installed in an electrophotographic imaging device. Background technique [0002] Commonly used electrophotographic imaging equipment (hereinafter referred to as "equipment"), such as printers, copiers, etc., use a laser beam loaded with target information to scan the surface of the photosensitive element to form an electrostatic latent image on the surface of the photosensitive element, and the surface is coated with a developer. The developing part is close to the surface of the photosensitive element, and uses the developer to develop the electrostatic latent image, and then the developer is transferred to the imaging medium. [0003] From the perspective of reducing the use cost of the end user, a developing cartridge in which the photosensitive element and the developing member are separately arranged has appeared on the market, that is,...

Problems solved by technology

[0005] Existingly, the component that the developing cartridge receives the driving force from the equipment is a power receiving part called a universal joint, one end of the power receiving part is installed on the developing cartridge, and the other end is connected with the power in the equipment. The output member combines and receives the driving force output by the power output member. One end of the power receiving member installed in the developing cartridge can rotate freely around its axis of rotation, that is to say, the combination of the power receiving member and the developing cartridge is not tight fit. During the entire life cycle of the cartridge, the power receiving member needs to be continuously combined and disengaged from the power output member. During such a large movement, the power receiving member has the risk of falling out of the developing cartridge
