Abstract
An image forming apparatus includes first and second conveyance and calculation units, a reverse unit, a control unit, an image forming unit, and a stack unit to stack sheets. A recording material is conveyed from the stack unit to the image forming unit. The recording material is conveyed reversely, and is conveyed to a double-sided conveyance path and to the image forming unit. Without causing a recording material to wait in the reverse unit, a first recording material is conveyed from the stack unit, then a second recording material is conveyed, and subsequently a third recording material is conveyed. A conveyance interval time and a maximum waiting time are calculated. When the conveyance interval time exceeds the maximum waiting time, the second recording material conveyance starts at timing based on a waiting time after conveyance of the first recording material, and the third recording material conveyance starts at a timing.
