Optical writing device and image forming apparatus |
摘要 |
An optical writing device for forming an electrostatic latent image on a photoreceptor by exposing the photoreceptor to light modulated in accordance with image data. The optical writing device has: a substrate; a light-emitting-element array including a plurality of light-emitting elements supported by the substrate to be arranged in a main-scanning direction; and a light-receiving-element array substantially in parallel to the light-emitting-element array, the light-receiving-element array including a plurality of light-receiving elements supported by the substrate to be arranged in the main-scanning direction. For light-quantity measurement of one of the light-emitting elements, at least an output value output from one of the light-receiving elements of which center is located in a different position, with respect to the main-scanning direction, from a center of the one of the light-emitting elements is used. |

1. An optical writing device for forming an electrophotographic image on a photoreceptor by exposing the photoreceptor to light modulated in accordance with image data, the optical writing device comprising:
a substrate; a light-emitting-element array including a plurality of light-emitting elements supported by the substrate to be arranged in a main-scanning direction; and a light-receiving-element array substantially in parallel to the light-emitting-element array, the light-receiving-element array including a plurality of light-receiving elements supported by the substrate to be arranged in the main-scanning direction; wherein for light-quantity measurement of one of the light-emitting elements, at least an output value output from one of the light-receiving elements of which center is located in a different position, with respect to the main-scanning direction, from a center of the one of the light-emitting elements is used. |
