Image forming apparatus

Abstract

An image forming apparatus in that a sheet having an image formed on a first side thereof by an image forming portion is again transported to the image forming portion so that an image may be formed on an opposite or second side of the sheet, the image forming apparatus including a sheet feeding portion for feeding the sheet to the image forming portion, a re-transport path along which the sheet having the image formed on the first side thereof and again transported to the image forming portion passes, a pair of registration rollers provided upstream of the image forming portion for contacting with the sheet fed from the sheet feeding portion or the sheet having passed along the re-transport path in a state in which the pair of registration rollers are at a halt and forming a loop in the sheet to thereby correct the skew feed of the sheet, and thereafter transporting the sheet toward the image forming portion at predetermined timing, and a loop forming space provided upstream of the pair of registration rollers so as to form the loop, wherein an entrance to the loop forming space for the sheet having passed along the re-transport path is formed downstream of an entrance to the loop forming space for the sheet fed from the sheet feeding portion.
