Abstract
A sheet feeding unit, attached to a sheet feeding apparatus that feeds a sheet, includes an endless belt, first and second rotary members, and a holding device. The endless belt contacts a sheet stacked on a stacking device to feed the sheet. The first and second rotary members contact an inner periphery of the endless belt to support the endless belt. The second rotary member faces, via the endless belt, a separation device that separates the sheet from the endless belt. The holding device holds the first and second rotary members. The endless belt includes protruding and depressed portions on the inner periphery. The second rotary member includes protruding and depressed driving portions that mesh with the protruding and depressed portions to transmit a driving force to the endless belt to, in turn, rotate the endless belt to feed the sheet in contact with the endless belt.
