Abstract
An image forming apparatus includes an image bearing member, a transfer member, a voltage applying portion applying a voltage to the transfer member, and a controller. The controller starts a control operation by applying a control voltage to the transfer member before a toner image is transferred to a transferred member from the image bearing member. On the basis of a coverage ratio indicating a ratio occupied by an image region per predetermined area regarding the toner image transferred to the transferred member from the image bearing member, the controller determines execution or non-execution of the control operation capable of being started before the toner image is transferred to the transferred member.
