    摘要： In an image forming apparatus that employs a system of charging by adjacent discharge, not only can degradation of the photoreceptor surface caused by adjacent discharge be prevented, but also there is no side effect on the developer, and at the same time size reduction is achieved. The image forming apparatus comprises an object to be charged whose surface moves; a charging device for charging the object to be charged using an electrical discharge generated by applying a voltage comprising an alternating current component to a charging member provided in contact with or in proximity to the object to be charged; a latent image forming device for forming an electrostatic latent image on the surface of the object charged by the charging device; and a developing device for causing a two-component developer to come into contact with the image portion of the electrostatic latent image formed by the latent image forming device and affixing toner thereto. A protective substance is present on the surface of the object to be charged in the discharge region for charging the object to be charged, and the saturation magnetization of the carrier of the two-component developer with respect to an applied magnetic field of 1000 oersted is 40 to 80 emu/g.
