Abstract
An actual sheet interval from a preceding sheet to a succeeding sheet is detected by a top sensor. A registration roller is accelerated or decelerated such that the sheet interval from the preceding sheet to the succeeding sheet is an ideal value by the time that the leading edge of the succeeding sheet reaches a transfer nip part. Note that a time period during which acceleration or deceleration is applied and a sub-scan synchronization signal output timing are determined from the actual sheet interval. Note that a recording sheet P does not stop at the registration roller.
