Abstract:
An image forming apparatus comprising:a photoreceptor having a substrate whose surface has 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, said exposure device having a light source for emitting a light beam, and carrying out exposure in a manner of dot arrangement through a main scanning by deflection of the light beam and a sub-scanning by a movement of the photoreceptor; a developing device for developing the latent image with a toner to form a toner image; and a transfer device for transferring the toner image onto a medium, wherein the exposure device carries out the exposure in the main scanning direction with a spatial frequency of dot arrangement pitch of not less than 4 dots/mm, and wherein a cross-sectional surface shape of the substrate in the main scanning direction has substantially no projections and concavities of a period corresponding to a feed pitch of the cutting tool used in the surface processing.
