Abstract
An image forming apparatus includes image forming units, a transfer unit that transfers a superposed toner image including toner images formed by the image forming units onto a sheet, a fixing unit that fixes the superposed toner image onto the sheet, and a controller that performs control such that a toner image is formed while the amount of toner used per unit area by the second image forming unit when forming a line image is smaller than that when forming a solid image. The image forming units include a first image forming unit that forms a toner image that is transferred onto the transfer unit relatively earlier than the other toner images and a second image forming unit that forms a toner image that is transferred onto the transfer unit relatively later than the other toner images, the first and second image forming units using the same color toner.
