PROBLEM TO BE SOLVED: To obtain an inexpensive image forming device having neither trouble caused by an ozone product nor trouble caused by faulty electrification, etc., and having simple constitution by realizing ozoneless direct injection electrifica tion at low applied voltage, which is more excellent in electrification uniformity and is stable over a long term, with the simple constitution even in the case of using a simple member such as a sponge roller as an electrifying member in contact electrification. SOLUTION: This electrifying member 2 forms a nip part (a) with a body to be electrified 1 through electrification accelerating particles (m) for accelerating the electrification of the body 1 and has an elastic layer for electrifying the surface of the body 1. The elastic layer has multilayer structure at least including three layers such as a 1st elastic layer 22, a conductive base layer 23, and a 2nd conductive elastic layer 24 in order from an opposite side to the side of the body 1 toward the side to the body 1, and the hardness of the layer 22 is lower than that of the layer 24.
