ABSTRACT:
In an image forming apparatus according to the invention, the potential of an optical semiconductor is increased in a predetermined time period, in which a recording medium does not exist in a transfer region between the optical semiconductor and a transfer unit, so as to set a difference between a developing bias voltage and the potential of the optical semiconductor larger than a difference therebetween assumed when toner is being transferred onto the recording medium.
