Abstract
An image forming apparatus on which a paper handling apparatus is detachably mountable is provided. The image forming apparatus includes an image processing section that processes an externally inputted image signal, an image forming section that forms an image on a paper sheet based on the image signal processed by the image processing section, and a control section that controls the image forming section based on an instruction from the image processing section, wherein the control section transmits to the image processing section a paper delivery signal indicating a timing to deliver paper sheets from the image forming section to the paper handling apparatus. The image processing section controls the paper handling apparatus based on the paper delivery signal received from the control section. The control section successively transfers a plurality of paper sheets at a first paper interval when images are successively formed on a plurality of paper sheets and the control section does not receive from the image processing section an instruction to transmit a paper delivery signal, and successively transfers a plurality of paper sheets at a second paper interval different from the first paper interval when images are successively formed on a plurality of paper sheets and the control section receives from the image processing section an instruction to transmit a paper delivery signal.
