Process cartridge and electronic photographing imaging equipment

Abstract

The invention provides a process cartridge and electronic photographing imaging equipment. The process cartridge comprises a drum frame, a developing frame, a photosensitive drum and a developing roller, wherein the drum frame is connected with the developing frame, the photosensitive drum can rotate around the axis thereof and is supported between two end walls of the drum frame, a photosensitivedrum driving head in joint with a first transmission head is arranged at one axial end of the photosensitive drum, the developing roller can rotate around the axis thereof and is supported between two end walls of the developing frame, and a developing roller driving head in joint with a second transmission head is arranged at one axial end of the developing roller; and an elastic element is arranged at a position close to a non-driving end on the bottom wall of the drum frame, the two sides of the elastic element are respectively against and connected with the bottom walls of the drum frameand a cartridge containing chamber, the photosensitive drum driving head and the first transmission head are coaxially arranged, and the developing roller driving head and the second transmission headare coaxially arranged. The process cartridge provided by the invention is simple in structure and easy to assemble, and smoothness of the process cartridge in a dropping process and a disassembly process is improved.

Description

technical field [0001] The invention relates to the technical field of electrophotographic imaging and printing, in particular to a process box detachably installed on an electrophotographic imaging device and an electrophotographic imaging device with the process box. Background technique [0002] Electrophotographic imaging equipment is a kind of equipment that uses the principle of electrophotography to form images on printing media such as paper, including copiers, printers, fax machines, all-in-one machines, etc., usually including a host and a processing box detachably installed in the host. Wherein, the processing box is provided with a rotating element and a rotating force transmission assembly that receives the rotating driving force provided by the main machine such as a printer. The rotating element includes at least one of a developing element, a photosensitive drum, and a charging element. After the processing box is installed on the main machine, it rotates The...
