Abstract
A sheet conveying apparatus for use in an image forming apparatus such as a copying machine has a sheet conveyance path defining member that defines a curved path along which a sheet is conveyed, a conveyor roller for conveying the sheet along the curved path, a reference position regulating member that engages with a reference side edge of the sheet so as to regulate the sheet position in the breadthwise direction of the sheet during conveyance of the sheet along the curved path, and a guide member for restricting the position of the reference side edge of the sheet in the direction of thickness of the sheet pressed onto the position regulating member. The conveyor roller cooperates with a skewed roller which produces a skewing urging force to bring the reference side edge of the sheet into pressure contact with the reference position regulating member. The guide member prevents the reference side edge of the sheet pressed to the reference position regulating member from buckling or curling into a gap between the reference position regulating member and the conveyor roller. The conveyor roller and the skewed roller are engageable only with a side portion of the sheet adjacent to t…
