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.
