Claim:
1. An image forming apparatus comprising: a feeding member configured to feed a recording material stacked on a stacking unit; a conveying member configured to convey the recording material fed by the feeding member; a separation member configured to separate recording materials so that one recording material is conveyed in a case where a plurality of recording materials are fed from the stacking unit by the feeding member; a detecting unit disposed on a downstream side of the conveying member in a conveyance direction of the recording material, and configured to detect the recording material; a controller configured to control the feeding member and the conveying member; and an image forming unit configured to form an image on the recording material conveyed by the conveying member, wherein the controller controls the feeding member to feed the recording material stacked on the stacking unit at a first speed, wherein, in a case where the detecting unit does not detect the recording material before a predetermined time has passed since the controller began controlling the feeding member to feed the recording material stacked on the stacking unit, the controller controls the conveying member to change a speed of the recording material from the first speed to a second speed that is faster than the first speed at a timing when the predetermined time has passed since the controller began controlling the feeding member to feed the recording material stacked on the stacking unit and the controller sets a length of a conveyance time to convey the recording material at the second speed based on a detection timing when the detecting unit detects the recording material, and wherein the controller sets a length of the predetermined time in such a manner that the recording material fed at the first speed reaches at least the separation member at the timing when the predetermined time has passed.
