Image forming apparatus |
摘要 |
An image forming apparatus includes a photoreceptor rotatable about an axis, and having a surface with a photosensitive layer abraded during use, a charging unit configured to charge the surface of the photoreceptor, an exposure unit configured to form an electrostatic latent image on the surface of the photoreceptor, a developing unit configured to form a toner image on the surface of the photoreceptor, and a control unit configured to obtain a film thickness of the photosensitive layer for each of a plurality of different positions in a direction of a rotation axis of the photoreceptor, and perform abrasion operation at a first or second position of the plurality of positions, when a difference in film thickness between the first position and the second position exceeds a predetermined reference value. |

1. An image forming apparatus comprising:
a photoreceptor rotatable about an axis, and having a surface with a photosensitive layer abraded during use; a charging unit configured to charge the surface of the photoreceptor; an exposure unit configured to form an electrostatic latent image on the surface of the photoreceptor; a developing unit configured to form a toner image on the surface of the photoreceptor; and a control unit configured to obtain a film thickness of the photosensitive layer for each of a plurality of different positions in a direction of a rotation axis of the photoreceptor, and perform abrasion operation at a first or second position of the plurality of positions, when a difference in film thickness between the first position and the second position exceeds a predetermined reference value. |
