PROBLEM TO BE SOLVED: To provide an image forming apparatus for forming a stable image, even when performing repeated use for suppressing friction amount reduction of a photoreceptor, while securing electrification uniformity by taking into considering account electrification hazard in the repeated use of the photoreceptor. SOLUTION: An electrophotographic device comprises at least an electrifying means, an exposure means, a development means, a transfer means and an electrophotographic photoreceptor. An electrifying member used for the electrifying means is a roller shaped electrifying member arranged near the photoreceptor. The electrophotographic photoreceptor is a photoreceptor performing electrification, by applying a voltage superposing a alternating voltage on a direct current voltage to the electrifying member.
