Abstract:
The present invention ensures stable cleaning performance with respect to remaining toner on an intermediate transfer belt without increasing the size and cost of an image forming apparatus. The present invention provides an image forming apparatus in which residual toner charged by a toner charging member is transferred from the intermediate transfer belt to a photosensitive drum, the toner charging member is placed with respect to the intermediate transfer belt in a rotation direction of the intermediate transfer belt such that a first distance of the intermediate transfer belt from a position where a secondary transfer member contacts the intermediate transfer belt to a position where the toner charging member contacts the intermediate transfer belt is longer than a second distance from the position where the toner charging member contacts the intermediate transfer belt to a position where an image bearing member placed most upstream contacts the intermediate transfer belt.
