PURPOSE:To provide the electrifying member which can stably supply high-trade images which are free from image dotty fogging by the nonuniformity of electrification and image defects by the discharge breakdown of a photosensitive body by providing a resin layer contg. a hydroquinone deriv. resin on a conductive elastic layer. CONSTITUTION:This electrifying member is made into the three-layered constitution consisting of the conductive elastic layer 2 provided on a conductive base 1a and further, the resin layer 3 contg. the hydroquinone deriv. resin on the elastic layer 2. Polyvinyl hydroquinone, hydroquinone/phenol/formalin copolymer resin, etc., are preferably used as the hydroquinone deriv. resin. Further, a binder resin may be added to the resin layer. The electrifying member having the resin layer contg. the hydroquinone deriv. resin in such a manner has the low adhesiveness to the electrophotographic sensitive body and has resilience as well and, therefore, the member imparts high image quality, lessens the contamination with toners, and lessens the fluctuation in the volumetric resistance of the resin layer even at and under a low temp. and low humidity. This member is thus usable as the stable electrifying member. |
