Abstract
A color image forming apparatus wherein the pre-secondary transfer electric charge eliminating device arranged intermediate between a primary transfer section and a secondary transfer section is provided with: a discharge electrode arranged on the side opposite to the toner carrier surface of an intermediate transfer member; and a counter electrode containing a discharge electrode and a conductive elastic member arranged at the opposed position beyond the intermediate transfer member so as to be pressed against the intermediate transfer member; wherein the pressing force of the aforementioned counter electrode against the rear surface of the intermediate transfer member is distributed in such a way that the pressure for the center of the intermediate transfer member is smaller than that for both ends thereof, in the transversal direction to the direction in which the intermediate transfer member rotates.
