Process cartridge and image forming apparatus

The invention relates to the technical field of image forming equipment, in particular to a processing box and image forming equipment. The process cartridge includes: a housing; the sealing cover isdetachably connected with the shell; the developing roller can rotate relative to the shell; the moving part is movably connected with the shell, and in the process that the moving part moves relativeto the shell, the developing roller can be driven to rotate; in the process that the sealing cover is installed on the shell, the sealing cover can drive the moving part to move in the first direction B, and at the moment, the developing roller can rotate forwards; in the process that the sealing cover is detached from the shell, the moving part can move in the second direction C so as to drive the developing roller to rotate reversely; and the first direction B is opposite to the second direction C. According to the processing box, the moving part is driven to move when the sealing cover isdisassembled and assembled
