PROBLEM TO BE SOLVED: To miniaturize a developing device. SOLUTION: This developing device has a developing roller 10d, and conductive flange members 20a and 20b fixed on the roller 10d, and is equipped with a fixed electrode member 25 coming into contact with a device-side contact (electrode) 26 provided in an image forming device and the metallic supporting member 10e1 of a developing blade (developer regulating member) 10e with electric conduction when the developing device is attached to the image forming device in a developing frame body on a driving side having a developing roller gear (driving means) 22 transmitting driving force from the image forming device to the roller 10d, and a 1st electrode 30 connecting the members 20a and 20b and the member 10e1 with the electric conduction in a developing frame body on the other non-driving side. Then, a feed path for applying voltage from the contact 26 provided on the driving side of the image forming device to the roller 10d is formed of the contact 26, the member 25, the member 10e1, the electrode 30 and the members 20a and 20b. |
