Abstract: An image forming apparatus is provided that can provide a natural edge processing even if a toner save processing and a line width correction processing are configured in parallel. The image forming apparatus detects an edge neighboring region of an input image in a predetermined direction. The edge neighboring region detected by the neighboring edge detection step is subjected to a line width correction processing. An edge region of the input image in a direction other than the predetermined direction is detected. Then, a toner save processing is performed on a no-edge region that is a region other than the edge region detected by the edge detection step.
