ABSTRACT:
An image forming apparatus is provided which includes a charging roller (2) for charging an image carrying medium (1) by coming in contact with the image carrying medium (1), a power source (21) for applying a reference voltage to the charging roller (2), a potential sensor (10) for detecting a charged voltage of the image carrying medium (1), a temperature sensor (11) for detecting environmental conditions of the charging roller (2), and a CPU (20) for controlling the power source (21) from a detection result obtained by the potential sensor (10) and a detection result obtained by the temperature sensor (11). The CPU (20) makes alterations to the reference voltage of the power source (21) so that the charge potential of the image carrying medium (1) can be brought to a target potential level, and sets an execution timing for the alterations.
