1. An image forming apparatus comprising:
a stacking unit on which a plurality of recording materials are stackable;
a feeding roller configured to feed the recording material stacked on the stacking unit;
an image forming unit configured to form an image on the recording material fed by the feeding roller;
a detecting unit configured to detect the recording material fed by the feeding roller toward the image forming unit; and
a controlling unit configured to control the image forming unit and the feeding roller, the controlling unit controlling a feed interval between the recording materials continuously fed by the feeding roller,
wherein the controlling unit sets the feed interval between a first recording material precedently fed and a second recording material subsequent to the first recording material to a first feed interval based on an image signal which is received, and
wherein, in a case that the detecting unit does not detect a trailing end of the first recording material with respect to a feeding direction after detecting the first recording material until a predetermined time elapses, the controlling unit sets the feed interval to a second feed interval longer than the first interval and determines a timing of image forming on the second recording material by the image forming unit based on the second feed interval.
