Abstract
An image forming apparatus includes an image bearing member configured to bear an electrostatic latent image on a surface thereof, a developing mechanism configured to develop the electrostatic latent image formed on the surface of the image bearing member into a toner image with toner, a transfer mechanism configured to transfer the toner image from the image bearing member to an image receiver, and a cleaning mechanism including a cleaning blade configured to scrape a residual toner on the surface of the image bearing member after the toner image is transferred to the image receiver, the cleaning blade disposed in contact with the image bearing member and having a JIS-A hardness equal to or more than 70 and a repulsion elasticity equal to or less than 30%, and a friction reducing member configured to reduce a coefficient of friction on the surface of the image bearing member.
