Abstract
An image forming apparatus includes an endless belt stretched over a plurality of rollers. The apparatus also includes a potential detecting device for detecting a potential of the endless belt. The detecting device is positioned downstream, along a sheet transport path, of a transfer position where the belt has direct contact with the image bearing member. The apparatus further includes a transferring member for transferring a toner image formed on the image bearing member to a sheet. An image forming process is halted when the potential detecting device does not detect a change in potential caused by presence of a sheet on the endless belt.
