Abstract
An image forming apparatus includes a process unit to form an image onto a sheet. A fixer fixes the image to the sheet. A reverse roller makes a positive rotation to convey the sheet in a forward direction from the fixer, and makes an opposite rotation to convey the sheet in an opposite direction. A returner returns the sheet to the process unit. A branching member guides the sheet from the reverse roller to the returner. A first sensor detects the sheet. The controller controls the reverse roller to make the positive rotation at a circumferential speed higher than a speed of the sheet conveyed by the fixer, controls the reverse roller to wait for predetermined waiting time after the first sensor has detected a rear end of the sheet, and makes the waiting time shorter as a length of the sheet is greater.
