Claim:
An image forming apparatus, comprising: an image forming unit configured to form an image on a recording medium; a stacking unit configured to stack recording media on which images are formed by the image forming unit; a first detection unit configured to detect a conveyance interval between a trailing edge of a first recording medium that is first conveyed and a leading edge of a second recording medium conveyed subsequent to the first recording medium; a second detection unit disposed downstream of the first detection unit with respect to a conveying direction of a recording medium and configured to detect the conveyance interval and detect whether an amount of recording media stacked on the stacking unit exceeds a predetermined amount; and a control unit configured to control, according to a result of comparing the conveyance interval detected by the first detection unit and the conveyance interval detected by the second detection unit, a conveyance interval between a trailing edge of a preceding recording medium and a leading edge of a succeeding recording medium so that the conveyance interval between the trailing edge of the preceding recording medium and the leading edge of the succeeding recording medium is wider than the conveyance interval detected by the first detection unit in a case where a third recording medium subsequent to the second recording medium is conveyed.
