摘要:
An image forming apparatus including an image bearing member that bears a latent electrostatic image on the surface thereof, a charging device that uniformly charges the surface of the image bearing member, an irradiation device 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 on the surface of the image bearing member with toner to form a toner image thereon, a transfer device that transfers the toner image to a transfer body, a cleaning device including a cleaning blade that removes residual toner remaining on the surface of the image bearing member with the cleaning blade, a protective agent application device that applies a protective agent containing zinc stearate and zinc palmitate to the surface of the image bearing member, wherein the ratio of the zinc stearate and the zinc palmitate is from 66:34 to 40:60 by weight.
