ABSTRACT:
In an image forming apparatus, an image processing device draws, when a start point, at least one bent point, an end point and a width of a bold line is input, the bold line by generating a plurality of rectangular areas based on a line connecting the start point and bent point, a line connecting the bent point and the end point, and the input width. Each rectangular area or box is generated such that the start and end points of a line lie at the center in the widthwise direction of the box, and such that the bent point lies at a corner of the box on the basis of the direction of rotation of the above line and a line contiguous therewith. The bent point therefore does not lie at the center of the box in the widthwise direction. When an area signal is generated based on the stored start and end points of each box in the main scanning direction, a blank is obviated despite that a bent point area is additionally generated.
