Abstract
There is provided an image forming apparatus including: a photosensitive member that is driven to rotate; an exposure head that includes a plurality of light-emitting portions arranged at different positions in an axial direction of the photosensitive member, wherein each of pixels of an image corresponding to an output resolution of the image forming apparatus is formed by multiple light-emitting portions of the plurality of light-emitting portions, and a control unit configured to control the number of light-emitting portions to be driven to form each of the pixels of the image based on correction data.
Claims17
An image forming apparatus comprising:
- a photosensitive member that is driven to rotate around an axis;
- an exposure head that includes a plurality of light-emitting portions arranged at different positions in an axial direction of the photosensitive member, wherein an image is formed by multiple light-emitting portions of the plurality of light-emitting portions;
- and
- a control unit configured to control driving of multiple light-emitting portions based on correction data, wherein
- the image includes at least first pixel and second pixel, and
- the control unit controls the driving of the multiple light-emitting portions based on the correction data such that a first number of light-emitting portions of the multiple light-emitting portions form the first pixel and a second number of light-emitting portions of the multiple light-emitting portions form the second pixel, the second number being different from the first number, and
- the control unit controls the driving of the multiple light-emitting portions based on the correction data such that a position of the second pixel is randomly selected in the axial direction.
