DEVELOPING DEVICE, PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE, AND POWER FEED COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a developing device in which space on the side of a contact point for power feed to a developing roller is saved and the reliability of a contact point part at the contact point for the power feed is improved. SOLUTION: A first conductive part 600 for electrically being connected with a main body conductive part provided for an electrophotographic image forming device main body is provided on a frame 63A. A second conductive part 500 entering a developing roller 12 from a hole 15b made in the shaft 10 of the developing roller 12 is also provided in the frame 63A. For electrical connection with the second conductive part 500, a third conductive part 400 is provided in the developing roller 12 so as to be slidable on the second conductive part 500.
