Abstract
An image forming apparatus includes a detection unit to detect recording material fed from a stacking unit, a determination unit, a count unit, and a control unit. The determination unit determines that a feeding failure has occurred when the detection unit does not detect the recording material until elapse of a predetermined period. The count unit counts a number of times the feeding operation is performed for a single sheet of the recording material. When the counted number of feeding operation performance times by when the feeding failure has occurred is smaller than a threshold, the control unit restarts the feeding operation that has been stopped without waiting for a user's operation. When the counted number of feeding operation performance times by when the feeding failure has occurred is at least equal to the threshold, the control unit waits for the user's operation while the feeding operation is stopped.
