<P>PROBLEM TO BE SOLVED: To shorten a drawing time. <P>SOLUTION: An image forming apparatus carries out a command analysis processing (e.g., band initialization command processing, threshold value table setting command processing, etc.), a halftone pattern production processing, and a square shape drawing processing in parallel. Concretely, the image forming apparatus includes a drawing device 105 for performing the halftone pattern production processing in which a halftone pattern is produced by performing a gradation processing using a threshold value, and a square shape drawing processing in parallel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
