Abstract
A contact charging type image forming apparatus, to which only a direct current voltage is applied, includes an electrophotographic photoreceptor that includes a conductive base material A and a photosensitive layer provided on the conductive base material A, and a charging member that includes a conductive base material B and an elastic layer provided on the conductive base material B, in which in a case where a dielectric film thickness of the electrophotographic photoreceptor is defined as L, and a resistance component of an impedance of the charging member in a range of 1 Hz or greater and 500 Hz or less, which is measured by an alternating current impedance method, is defined as R, Expression (1) is satisfied.
