摘要：
An electric contact member (29) for applying a development bias voltage to a development sleeve (12) for developing an electrostatic latent image formed on an electrophotographic photosensitive drum (7) which electric contact member is used by being attached to a flange (28) to be attached to an end portion of the development sleeve. The electric contact member (29) includes: a coil spring portion (29b) for being electrically connected with a frame side electrode (30) provided on a frame (13) supporting the development sleeve, which coil spring portion is projected from one end portion of the flange when the electric contact member is attached to the flange; a contact portion (29a) for contacting with an inner surface of the development sleeve when the flange, to which the electric contact member is attached, is attached to the end portion of the development sleeve, which contact portion is to be projected from the other end portion of the flange; and a connecting portion (29c) for connecting the coil spring portion and the contact portion, which connecting portion is disposed in the inside of the flange when the electric contact member is attached to the flange.
