Abstract
An image forming apparatus for performing image formation on a fed sheet includes a feeding unit, a detecting unit, a conveying control unit, and a first, second, and third determining unit. The feeding unit feeds a sheet of an irregular size onto a conveyance path. The detecting unit detects timings at which a leading edge and trailing edge of the fed sheet pass through a conveyance path predetermined position. The first determining unit determines a length of the sheet in a width direction. The conveying control unit discharges the sheet to a discharge destination without performing image formation on the sheet. The second determining unit determines a length of the sheet in the conveyance direction. The third determining unit determines a sheet size of the sheet of the irregular size from the length of the sheet in the width direction and the length of the sheet in the conveyance direction.
