| 摘要 | An image forming apparatus for forming an image by scanning an image bearer with light modulated in accordance with image information includes a light source configured to emit the light and a control device configured to control the light source in accordance with the image information. The control device sets light emission duration of the light source for forming a particular pixel in the image to be shorter than light emission duration of the light source for forming a normal pixel, which is a pixel other than the particular pixel irk the image, and sets light emission intensity of the light source for forming the particular pixel to be higher than light emission intensity of the light source for forming the normal pixel. | ||

| 主权项 | 1. An image forming apparatus for forming an image by scanning an image bearer with light modulated in accordance with image information, the image forming apparatus comprising: a light source configured to emit the light; and circuitry configured to: control the light source in accordance with the image information,set light emission duration of the light source for forming a particular pixel in the image to be shorter than light emission duration of the light source for forming a normal pixel, the normal pixel being a pixel other than the particular pixel in the image,set light emission intensity of the light source for forming the particular pixel to be higher than light emission intensity of the light source for forming the normal pixel, andselectively set a phase of the particular pixel. | ||
