    摘要: An optical writing device is configured to form electrostatic latent images on a plurality of photosensitive elements by a plurality of light sources. The optical writing device includes: an image-data acquiring section that acquires image data; and a light-source control section that performs light-emission control on the light source based on pixel data generated from acquired image data, and also performs a neutralization process on the photosensitive element by controlling the light source to expose the photosensitive element to light. In the neutralization process, the light-source control section divides a period during which light-on/off control can be performed on the light source, into sub-periods based on pixel data input to the light-source control section, and causes the light sources to be lit in any one of the sub-periods so as to always place at least one of the plurality of light sources in a light-off state.
