Provided are an electrophotographic member having excellent durability and an electrophotographic image forming apparatus. The electrophotographic member includes: an elastic layer including a silicone rubber; an intermediate layer including at least one of an aromatic polyimide and an aromatic polyamideimide, and a fluororesin; and a surface layer including a fluororesin, in which the aromatic polyimide or the aromatic polyamideimide is bonded to the silicone rubber through an amide bond-containing group, and in which a carbon atom constituting the amide bond is directly bonded to a carbon atom constituting an aromatic ring in a molecule of the aromatic polyimide or aromatic polyamideimide.

There is disclosed a liquid developing method of a printed wiring board using a one-surface stepwise developing system which forms a resist pattern stepwisely according to an electrophotographic reverse developing method on each surface of a material to be developed obtained by forming photo-conductive layers on both surfaces of a both-surfaces copper-clad laminated board, wherein the method comprises the steps of subjecting to a static charging treatment on a surface to which no electrostatic latent image is formed which surface is positioned opposing to an electrostatic latent image-formed surface which is a surface to be exposed, or to a non-developing surface between completion of an exposure treatment and before a liquid toner developing treatment, and subjecting to the liquid toner developing treatment to form a toner image corresponding to the resist pattern on the electrostatically latent image-formed surface.
