Image forming apparatus with pixel density based light beam control |
摘要 |
An image forming apparatus which includes an image bearing body and a light beam scanner for exposing the image bearing body, which is charged, based on an image signal and forming an electrostatic latent image on the image bearing body. A rise time or a fall time of a light beam emitted from the light beam scanner is controlled when a pixel density of the electrostatic latent image is switched.
