IMAGE FORMING APPARATUS AND EXPOSING APPARATUS |
| 摘要 |
An image forming apparatus includes a light scan head having a plurality of LED elements disposed along a main-scanning direction of a photoreceptor drum and configured to expose the photoreceptor drum with light, a developing device disposed to face the photoreceptor drum in the main-scanning direction and including a development roller configured to supply a developer to the photoreceptor drum, and a non-uniform density correction unit configured to control an intensity of light emitted from the plurality of LED elements of the light scan head based on correction data that corresponds to a tendency pattern of an expected non-uniform image density so as to correct the non-uniform density of an image that is to be formed on a recording medium. |

1. An image forming apparatus, comprising:
a light scan head including a plurality of LED elements, disposed along a main-scanning direction of a photoreceptor drum, configured to expose the photoreceptor drum with light; a developing device, disposed to face the photoreceptor drum in the main-scanning direction, including a development roller configured to supply a developer to the photoreceptor drum; and a non-uniform density correction unit configured to control an intensity of the light emitted from the plurality of LED elements of the light scan head based on correction data that corresponds to a tendency pattern of an expected non-uniform image density of an image that is to be formed on a recording medium caused by change in an adhesion amount of the developer which is supplied to the photoreceptor drum from the developing device when transferring a toner image on the photoreceptor drum to the recording medium. |
