IMAGE FORMING APPARATUS AND EMISSION CONTROL METHOD |
| 摘要 |
An image forming apparatus comprises: a plurality of exposure units, each of the exposure units including a plurality of light emitting elements that are arranged in a main scanning direction; a calculating unit that, with respect to each of the exposure units, calculates a pre-charge period that is a period during which a pre-charge is performed on at least any of the light emitting elements included in a corresponding exposure unit; and an emission control unit that, with respect to each of the exposure units, causes the light emitting elements included in a corresponding exposure unit to emit light such that a pre-charge period of at least any of the exposure units is shifted with respect to pre-charge periods of remaining ones of the exposure units. |
