Abstract
An image forming apparatus prevents the current of a transfer memory by providing a sufficient margin to accommodate any variation in feeding and timing without limiting the diameter of a photoreceptor. A transfer current controlling unit is included for controlling the transfer current applied to the transfer device and for controlling a TC high-voltage source control unit so that a transfer high-voltage source of the transfer device performs a stepwise current application in the raising process of a transfer output.
