Image forming apparatus

Abstract

An image forming apparatus including a photosensitive member, an intermediate transfer material, a first transfer device which transfers on the intermediate transfer material an image formed on the photosensitive member, a second transfer device which transfers on a sheet the image formed on the intermediate transfer material, a feed device which feeds the sheet to the second transfer device, a refeed device which refeeds the sheet, on which the image is transferred by the second transfer device, to the second transfer device with reversing the sheet, and a controller which executes selectively a first mode, in which one image is formed on one round of the intermediate transfer material, and a second mode in which two images are formed on one round of the intermediate transfer material, wherein the controller makes an image, which should be formed on a sheet refed by the refeed device, formed on a first half area on one round of the intermediate transfer material, and makes an image, which should be formed on a sheet fed by the feed device, on a second half area on one round of the intermediate transfer material, in a case of executing the second mode when performing image formation on both sides of a sheet, and wherein the controller executes the first mode before returning to the second mode after executing the first mode instead of executing the second mode when performing image formation on both sides of a sheet.
