Abstract
An image forming apparatus includes a stacking portion including a lifting portion, a feeding member feeding a sheet stacked on the lifting portion to a conveyance passage, a position detector detecting movement of the sheet stacked on to a feedable position to the conveyance passage, a driver including a motor and performing the lifting operation of the lifting portion, a rotation detector detecting rotation of the motor, and a controller. The controller determines a factor that the position detector does not detect the movement of the sheet stacked on the lifting portion to the feedable position within a predetermined time based on a detection result of the rotation detector while controlling the driver to lift up the lifting portion.
