Abstract:
1. An image forming apparatus comprising: an image bearing member; a charging unit that charges the image bearing member; a developing unit that develops an electrostatic latent image formed by exposing a surface charged by the charging unit and forms a toner image; a toner image detecting unit that detects the toner image on the image bearing member; a belt member in contact with the image bearing member; a transfer member for transferring the toner image on the image bearing member onto the belt member or onto a recording material on the belt member; and a control unit capable of outputting a state of the belt member on the basis of the result of detection by the toner image detecting unit, of a toner image formed by charging the image bearing member by applying a voltage to the transfer member, and developing a region charged by the transfer member using the developing unit.
