Patent ID: 8049931

Claim:
An image forming apparatus for forming an image on a transfer sheet based on image data, comprising: an operating section to set a margin region at an edge portion of the transfer sheet on which an image is not formed at the edge portion of the transfer sheet, a control section to determine an inner region having a specified width and being adjacent to the determined margin region as a density change region in which an image density is changed, and determines a more inner region located inward from the density change region as a regular density region in which an image is formed with a regular image density, and an image forming section to form an image on the density change region based on image data on the condition where the image density is reduced and to form an image on the regular density region based on image data without changing the image density, wherein the image forming section comprises a photoreceptor having an image forming surface and a toner image forming section to form a toner image, and wherein the image forming section sets an image forming region corresponding in size to the transfer sheet on the image forming surface of the photoreceptor and further sets the margin region, the density change region and the regular density region on the image forming region in accordance with the setup of the operating section and the determination of the control section, the toner image forming section is controlled so as not to form a toner image on the margin region, to form a toner image with the reduced image density on the density change region, and to form a toner image with the regular image density on the regular density region, and the image forming section transfers the toner images formed on the image forming region onto the transfer sheet.
