<p>An image forming apparatus (300) connected to a conveying-speed-changeable sheet post processing device (350) includes a discharging unit which discharges a sheet in a reverse discharge mode with front and back surfaces of the image-formed sheet reversed, and a non-reverse discharge mode without front and back surfaces of the image-formed sheet reversed, and discharges the sheet to the device (350) at a first speed or a second speed lower than the first speed; and a control unit which controls the discharging unit to discharge the sheet at the first speed in the reverse discharge mode, and discharge the sheet at the second speed in the non-reverse discharge mode. When a previous sheet is discharged at one of the first speed and the second speed, the control unit controls the discharging unit to discharge a next sheet at the same speed as the previous sheet, regardless of which mode the next sheet is to be discharged in.</p> |
