  • Publication number: 20210240124
    Abstract: An image forming apparatus comprises an image carrier to rotate about a rotation axis, a cleaning blade to contact a surface of the image carrier, and a protective agent coater. The protective agent coater has a rotatable shaft extending along the rotation axis of the image carrier, an elastic body formed around the rotatable shaft, and a waste toner supply member. The waste toner supply member supplies waste toner to the elastic body of the protective agent coater. The elastic body transfers protective agent from a protective agent supply to the image carrier. The protective agent coater is positioned upstream of the cleaning blade in the rotation direction of the image carrier.
