ABSTRACT:
An image forming apparatus includes a recording sheet transporting member which transports a recording sheet while holding the recording sheet thereon, the recording sheet transporting member being endless, a recording sheet re-feeding member which inverts the recording sheet and re-feeds the inverted recording sheet to the recording sheet transporting member to thereby allow transferring images on both sides of the recording sheet, and a recording sheet supplying member which supplies the recording sheet from a recording sheet storing portion toward the recording sheet transporting member. The apparatus further includes a controller which controls the recording sheet supplying member so that a supplying of the recording sheet from the recording sheet storing portion is interrupted and then re-tried in a predetermined case. The controller corrects a re-try timing at which the supplying of the recording sheet is re-tried so that the recording sheet being re-tried to be supplied by the recording sheet supplying member does not overlap the inverted recording sheet re-fed by the recording sheet re-feeding member.
