Patent ID: 7392008

Claim:
An image forming apparatus, comprising: an image bearing member; a charging device configured to charge a surface of the image bearing member; a light irradiating device configured to irradiate the charged surface of the image bearing member with light to form an electrostatic latent image on the surface of the image bearing member; a developing device configured to develop the electrostatic latent image with a developer including a toner to form a toner image thereon; a primary transfer device configured to transfer the toner image on the image bearing member to a surface of an intermediate transfer medium; a secondary transfer device configured to transfer the toner image on the intermediate transfer medium to a receiving material; a first cleaning device configured to clean the surface of the image bearing member; a second cleaning device configured to clean the surface of the intermediate transfer medium; a first lubricant application device configured to apply a first lubricant to the surface of the image bearing member such that the surface of the image bearing member has a first static friction coefficient; and a second lubricant application device configured to apply a second lubricant, which is different from the first lubricant, to the surface of the intermediate transfer medium such that the surface of the intermediate transfer medium has a second static friction coefficient higher than the first static friction coefficient, wherein the first static friction coefficient is not greater than 0.25 and the second static friction coefficient is from 0.30 to 0.45.
