Patent ID: 6853834

Claim:
An image forming apparatus comprising: a photoreceptor comprising: an electroconductive substrate, a photosensitive layer comprising a charge generation material and a charge transport material, and overlying the electroconductive substrate, and a protection layer comprising an inorganic filler in an amount of from 3 to 25% by weight based on total weight of the protection layer and a binder resin, and overlying the photosensitive layer; a charger configured to charge the photoreceptor; an irradiator configured to form an electrostatic latent image on the photoreceptor; an image developer configured to develop the electrostatic latent image with a developer comprising a toner to form a toner image on the photoreceptor; a transferer configured to transfer the toner image onto a transfer material; and a cleaner configured to clean the photoreceptor, comprising a rotatable core and a looped brush fiber provided on the surface of the rotatable core so as to contact the photoreceptor, wherein a top of the looped brush fiber is positioned on an upstream side from a root of the looped brush fiber relative to a rotating direction of the rotatable core.
