Abstract
The object of the present invention is to provide an image forming apparatus capable of producing excellent images without transfer irregularities regardless of impedance fluctuation dependent on transfer timing, and which avoids enlargement of the apparatus. The aforesaid objects are attained by the image forming apparatus of the present invention which sequentially transfers toner images formed by a plurality of image forming units onto the same transfer sheet via a plurality of transfer charging means, wherein transfer output is controlled in accordance with the change of impedance of the transfer area dependent on the timing of each transfer.
