ABSTRACT:
An image forming apparatus includes an image forming unit configured to form a toner image on an image bearing member, an endless belt configured to transfer and carry the toner image thereon, a transfer unit configured to transfer the toner image carried by the endless belt onto a recording sheet, a sensing unit configured to sense the toner image transferred onto the endless belt, a blocking unit mounted between the sensing unit and the endless belt and configured to block the sensing unit, a contact and separation unit configured to cause the transfer unit to reciprocally contact and separate from the endless belt. With this configuration, the blocking unit and the contact and separation unit are configured to be driven by an identical drive source.
