Abstract:
1. An image writing device comprising: a plurality of light-emitting-element array units including an image-data transfer controller that divides one line of image data for each of the light-emitting-element array units, transfers the divided image data to respective light-emitting-element array units, to drive each of the light-emitting elements in the light-emitting-element array units for an exposure in a main-scanning direction, wherein the image-data transfer controller performs a plurality of data transfers during one-line interval in the main-scanning direction, while performing a data processing of the one line of image data in the respective light-emitting-element array units, to drive the light-emitting element array, and the image-data transfer controller performs a pattern recognition according to one-line control in the main-scanning direction in the data processing.
