In a line by line image forming apparatus, line switching information which depends on scan line curve and an overlap data length to be read that overlaps across a plurality of lines before and after a switching position instructed by line switching information are set in a register (501). If switching to the line above or below is instructed by the line switching information, an address generating unit (502), when reading image data from an image memory, generates the read address and read data length of the image memory (304) in accordance with the line switching information and the overlap data length, and reads image data corresponding to a current line and the line above or below the current line in accordance with the generated data. |
