Abstract:
1. An image forming apparatus having an exposure unit configured to scan an image carrier with irradiation light based on image data, comprising: a storage unit; a plurality of data retention units configured to respectively correspond to different addresses in a subscanning direction of the storage unit; an input unit configured to input image data; a writing unit configured to write pixel data of the image data input by the input unit to the plurality of data retention units, based on curve information for correcting a curve of a scanning line of the irradiation light; a control unit configured to control, when the writing unit writes a predetermined number of pixel data to a specific one of the plurality of data retention units, the specific one of the plurality of data retention units to output the predetermined number of pixel data to an address in the subscanning direction of the storage unit, which corresponds to the specific one of the plurality of data retention units; and a transfer unit configured to transfer the pixel data of the image data stored in the storage unit in units of lines to the exposure unit.
