Abstract

PURPOSE:To improve image forming efficiency by detecting the arrival at a specified position of a first piece of paper after a first image formation processing and then switching to a second image forming operation. CONSTITUTION:The paper after the first image formation is either not passed through a switchback path 17 or passed through it according to a both surface mode or a synthetic mode, and then fed to a paper refeeding path 9 and integrating it in a carrying path without stopping. Then when the foremost paper which is supplied for image forming again through the paper refeeding path 9 reaches the specified position before an image forming part 6 and is detected by a sensor S3, and there is this detection, it is switched to an action of next image formation where no new paper feeding is carried out. Therefore, maximum quantity of paper responding to the image information quantity and the processing ability of an image forming controller 31 is held inside while carrying out the image forming operation, and layering of paper refed responding to the both surface or the synthetic mode with the newly fed paper is evaded. Thus, image formation of a multiple number of paper in the both surface or the synthetic mode can be carried out with high efficiency.
