ABSTRACT:
An image forming apparatus that effectively reduces sheet collision and increases productivity includes a storage unit to store sheets of a recording medium, a feeder to feed the sheets one by one from the storage unit, a conveyance device to convey the sheets along a conveyance path, a plurality of sensors to detect the sheets, a registration device to perform registration to the sheets, and a controller to control the feeder, the conveyance device, and the registration device. When a first sheet is stopped at or before it reaches the registration device, the feeder feeds a second sheet to the conveyance path, while the controller checks an interval between the first and second sheets. The controller stops the second sheet when the interval is shorter than a given interval and conveys the second sheet to the registration device without stopping when the interval is not shorter than the given interval.
