When a user changes a density adjusting value (developing contrast), and even variations and usage state of the process characteristics (photosensitive body and developing) of the cartridge change, the amount of recording agent consumed can be suppressed low, and a sharp line image can be recorded. An image forming apparatus of this invention includes an edge detecting portion for detecting an edge of image data, an image data correcting portion for correcting image data inside the edge so as to decrease its density, a laser driving circuit for forming an electrostatic latent image on a photosensitive body, and a correction value determining table for acquiring an instruction value for giving an instruction to correct a density contrast, wherein a correction condition for image data changes in accordance with an instruction value.
