Image forming apparatus, method of manufacturing substrate for photoreceptor, substrate for photoreceptor, and photoreceptor
An image forming apparatus, which includes a photoreceptor having a substrate whose surface having been subjected to a surface processing with a cutting tool, and a photosensitive layer formed on the substrate; an exposure device for exposing an image on the photoreceptor to form a latent image, having a light source for emitting a light beam, and carrying out exposure in a manner of dot arrangement through a main scanning by the deflection of the light beam and a sub-scanning by a movement of the photoreceptor; a developing device; and a transfer device. The apparatus is characterized in that the exposure device carries out scanning exposure with a spatial frequency of dot arrangement pitch of not less than 4 dots/mm in the main scanning direction, and surface roughness Rz of the substrate in the main scanning direction is not greater than 1.5 &mgr;m.
