Abstract
An image forming apparatus includes a sheet storage unit, a sheet feeding unit, a conveyance path for conveying a sheet to the image forming unit, a plurality of sheet detection sensors disposed along the conveyance path, a determination unit for determining whether predetermined time elapses from a detection of a front end of the sheet until a detection of a rear end of the sheet and a discharge unit. When the determination unit determines that the predetermined time has elapsed based on the detection by the sheet detection sensor disposed in the furthest upstream position among the plurality of sheet detection sensors, the sheet is discharged from the discharge unit, and when the determination unit determines that the predetermined time has elapsed based on the detection by the sheet detection sensors other than that disposed in the furthest upstream position, the sheet is stopped.
