Abstract:
A sheet feeding apparatus comprising:a discharge rotary body for feeding and discharging a sheet from a recording section;a pinch rotary body disposed facing the discharge rotary body for pinching and feeding the sheet along the discharge rotary body;a drive transmission rotary body having a circumferential surface contacting a circumferential surface of the discharge rotary body with a pressure exerted in a direction different from a straight line drawn between rotary centers of the discharge rotary body and the pinch rotary body, for rotationally driving the discharge rotary body; anda regulation member contacting the discharge rotary body when deformation of the discharge rotary body exceeding a predetermined quantity arises by pressure from the drive transmission rotary body and regulating deformation of the discharge rotary body from exceeding the predetermined quantity, wherein the regulation member is spaced from the discharge rotary body at a distance d which is set to meet e.ltoreq.d.ltoreq.(3/2)e where e represents a maximum permissible deformation amount for the discharge rotary body.
