摘要:
An image forming apparatus includes an image bearing member configured to bear a toner image, a protective layer forming device configured to apply a protective agent to a surface of the image bearing member with a brush-shaped protective agent applicator, and a surface roughness maintainer configured to maintain a surface roughness Ry of a contact surface of the protective agent with the brush-shaped protective agent applicator at 500 μm or less. The protective agent is a solid material in which a granular material comprising a fatty acid metallic salt is compressed.
