An image forming apparatus comprising:
- an image bearing member that bears a latent electrostatic image;
- a charging device that charges a surface of the image bearing member;
- an irradiator that irradiates the surface of the image bearing member to form the latent electrostatic image thereon;
- a development device that develops the latent electrostatic image with a development agent comprising a toner to form a visualized image;
- a transfer device that transfers the visualized image to a recording medium;
- a cleaning device having a cleaning blade having a front end that removes the toner remaining on the surface of the image bearing member, with a lubricant comprising boron nitride being attached to the front end;
- and
- a protective agent supplying device that supplies a protective agent comprising metal soap to the surface of the image bearing member,
- wherein an average attachment amount of the boron nitride in an area where the lubricant is attached is from 0.01 to 1 mg/cm2.
