Abstract
An image forming apparatus includes a patch image generation unit which generates a patch image for image density detection disposed between toner images, and a patch density sensor which detects a density of the patch image. In order to prevent the output quality of a printed image from varying with the type of paper use, a correction unit performs correction processing to match a detected density and a target density by comparing the detected density of the patch image detected by the patch density sensor and the target density of the patch image which is set in advance, a toner deposit control unit controls a toner deposit when the image forming unit forms an image based upon image data and when the patch image generation unit generates the patch image, and a paper interval control unit controls an interval between consecutive papers.
