ABSTRACT:
A sheet feeding device comprises a sheet feeding roller, having a first circumferential section and a second circumferential section, configured to rotate in a direction from the first circumferential section to the second circumferential section; and a pressure plate provided apart from the sheet feeding roller and configured to mount thereon a recording sheet stack having recording sheets ranging from a maximum number to a minimum number. The first circumferential section includes a first contact point for contacting, when the sheet feeding roller is rotated, a leading top edge of the recording sheet stack having the maximum number of recording sheets; and a second contact point for contacting, when the sheet feeding roller is rotated, a leading top edge of the recording sheet stack having the minimum number of recording sheets.
