  • PAPER FEEDING APPARATUS AND IMAGE FORMING APPARATUS
    Publication number: 20160282786
    Abstract: A sheet cassette includes a housing, a cassette bottom plate, a side regulation plate, and a DF prevention plate. Spacers are respectively arranged at three portions, that is, the center and both sides of the cassette bottom plate on the sheet feeding side. When a curled release sheet is placed on the sheet cassette, the spacers partially support the front end of the release sheet in the sheet feeding direction from below. Therefore, force acts on the release sheet to suppress the height of the curl by the own weight of the release sheet. When the curl of the release sheet is suppressed, the curled release sheet is stably fed.
