ABSTRACT:
A sheet feeding device includes a conveyor belt having a first row of a plurality of convex portions intermittently arranged on an inner circumferential surface of the conveyor belt in a sheet conveying direction. The sheet feeding device further includes a plurality of rollers around which the conveyor belt is spanned such that a direction substantially perpendicular to the sheet conveying direction is parallel to an axial direction of each of the rollers. The rollers include concave portions on outer circumferential surfaces thereof, in which the convex portions of the first row of the conveyor belt are engaged. The concave portion of at least one roller of the plurality of rollers has a width different from a width of each of the plurality of rollers other than the at least one roller.
