Image forming apparatus and image forming method

An image forming apparatus forming an image using electrophotography, comprising:

• an image forming section having a photoreceptor having on its surface a photosensitive film for forming an electrostatic latent image and a developing section for forming a toner image by supplying a toner onto the electrostatic latent image on the photoreceptor surface;
• a correcting section executing a plurality of correction processings for performing image quality adjustment of an outputted image of the image forming section, a history storage section for storing a history of execution of the plurality of correction processings;
• and
• a selection section selecting the correction processing to be executed from the plurality of the correction processings based on the history,
• wherein the plurality of correction processings comprises a high density correction processing as an essential processing, and a halftone correction processing and a registration correction processing as optional processings, and
• wherein the selection section refers to a history of the halftone correction processing and the registration correction processing and selects from the halftone correction processing and the registration correction processing the one whose latest execution is earlier than that of the other.
