Abstract
A sheet feeding apparatus has a sheet container which contains sheets and is removably mounted to a main body of the sheet feeding apparatus, a separation device including a conveyer and a separation member are urged against the conveyer with a predetermined separating pressure to separate the sheets fed out from the sheet container one by one, and a pressure increasing unit for increasing contact pressure between the conveyer and the separation device above the predetermined separating pressure. The pressure increasing unit increases the contact pressure until the mounting of the sheet container to the body of the sheet feeding apparatus is completed so that, even if the sheet container is inserted into the sheet feeding apparatus vigorously, the sheets are prevented from entering between the conveyer and the separation member, thus preventing poor sheet separation.
