An electrophotographic apparatus includes a photosensitive member and an electrostatic image forming apparatus for forming an electrostatic image on the photosensitive member. The electrostatic image forming apparatus includes a charging device for electrically charging the photosensitive member and an exposure device for exposing the photosensitive member charged by the charging device. A developing device forms a toner image by developing the electrostatic image with toner. A transfer device electrostatically transfers the toner image onto a transfer material, wherein the photosensitive member has characteristics such that a rate of change of surface potential of the photosensitive member relative to a change of an exposure amount of the photosensitive member, is smaller in the case of a first exposure amount than in the case of a second exposure amount which is larger than in the first exposure amount. A reducing device reduces a potential difference between a potential of the photosensitive member at the portion to which the toner is deposited and the potential of the photosensitive member of a portion to which the toner is not deposited after a developing operation of the developing device and before a transfer operation of the transfer device.
