Abstract:
An image forming apparatus, comprising:an image bearer for bearing an image formed on a transferring material; a charging portion for charging said image bearer with predetermined potential; an exposing portion for forming an electronic latent image by exposing an image forming area of said image bearer charged with the predetermined potential; a developing portion for developing an electronic latent image on said image bearer to form on said image bearer an image to be formed on the transferring material, wherein a voltage set in said developing portion for the image forming area of said image bearer is different from a voltage set in said developing portion for a non-image-forming area of said image bearer; a transferring portion for transferring an image formed on said image bearer by said developing portion to the transferring material; a transferring current detecting portion for detecting a transferring current flowing through said transferring portion; and a controlling portion for controlling a voltage set in said developing portion, wherein a voltage set in said developing portion for the non-image-forming area of said image bearer is controlled based on a transferring current value detected by said transferring current detecting portion.
