ABSTRACT:
In a transport belt drive control device, a first detection unit has a first resolution and indirectly detects a feed amount of a transport belt, a control unit controls drive of the transport belt based on an output of the first detection unit, and a second detection unit has a second, lower resolution and directly detects the feed amount of the transport belt. The control unit is configured to switch, when an output of the second detection unit is determined as not allowing detection of a stop position of the transport belt, the direct detection of the belt feed amount by the second detection unit to the indirect detection of the belt feed amount by the first detection unit, so that the drive of the transport belt is controlled based on the output of the first detection unit.
