ABSTRACT:
A paper feeder is suitable for use in an image forming apparatus such as a copier, a printer or the like and is capable of suitably correcting the direction of a sheet of paper conveyed from a registration device to a transfer unit. A paper conveying path is provided in curve form between a resist roller pair and a conveying roller pair provided on the upstream side of the resist roller pair as seen in a paper feeding direction. A fixed guide member is provided on the concave side of the paper conveying path. A movable guide member rotatably supported by a rotatable shaft with the rotatable shaft taken as the center, is provided on the convex side of the paper conveying path. The movable guide member is urged toward the fixed guide member by a torsion spring. A film-shaped elastic member which extends toward the downstream side as seen in the paper conveying direction, is mounted on a leading end portion of the movable guide member. Thus, a force for pressing the leading end portion of the paper against the resist roller pair suitably acts on the paper so that the oblique feeding of the paper is reliably corrected.
