IMAGE FORMING APPARATUS
First Claim
1. An image forming apparatus comprising:
- at least one photoreceptor configured to bear an electrostatic latent image thereon, wherein the photoreceptor includes an electroconductive substrate, a photosensitive layer located overlying the substrate, and an outermost layer having projected portions thereon, wherein the outermost layer and the projected portions include a same crosslinked charge transport material, and wherein the outermost layer has a surface roughness property such that a number of projected portions having a height greater than Rz/2 is from 40 to 90 in a measurement length of 12 mm, wherein Rz represents ten-point mean roughness of a surface of the outermost layer and is determined by a method defined in JIS B0601 (2001);
a developing device configured to develop the electrostatic image with a developer including a toner to form a toner image on a surface of the photoreceptor;
a transferring device configured to transfer the toner image onto a receiving material; and
a cleaning device having a cleaning blade configured to clean the surface of the photoreceptor after the toner image is transferred, wherein a tip edge line of the cleaning blade is contacted with the surface of the photoreceptor at a linear pressure of from 80 g/cm to 150 g/cm.

Abstract
The image forming apparatus includes a photoreceptor bearing an electrostatic image; a developing device developing the electrostatic image with a developer including a toner to form a toner image on the photoreceptor; a transferring device transferring the toner image onto a receiving material; and a cleaning device having a cleaning blade cleaning the surface of the photoreceptor. The photoreceptor includes an electroconductive substrate, a photosensitive layer and an outermost layer having projected portions thereon. The outermost layer and projected portions include the same crosslinked charge transport material. The outermost layer has a surface roughness property such that the number of projected portions having height greater than Rz/2 is from 40 to 90 in a length of 12 mm, wherein Rz represents ten-point mean roughness of the outermost layer. The tip of the cleaning blade is contacted with the photoreceptor at a linear pressure of from 80 g/cm to 150 g/cm.
