Abstract:
1. An image forming apparatus comprising: an image forming unit that forms a toner image based on image data; a conveyor unit that conveys a transfer medium onto which the toner image is to be transferred; a printing unit that prints the toner image onto the transfer medium; a detecting unit that detects a print command for each image including information on printing mode, the printing mode including single-sided printing and double-sided printing; a data acquiring unit that acquires, when the detecting unit detects a print command for an image, image data of the image, and outputs the image data to the image forming unit; a first control unit that controls the conveyor unit to feed a transfer medium from a feed tray to the printing unit in response to a first print command for printing a first side of the transfer medium by double-sided printing, and to feed the transfer medium to the printing unit from a conveying path, where the transfer medium is temporarily kept after the first side is printed, in response to a second print command for printing a second side of a previous transfer medium by double-sided printing; and a second control unit that controls the conveyor unit to convey the transfer medium to the conveying path after the first side of the transfer medium is printed, and to eject the previous transfer medium after the second side of the previous transfer medium is printed, wherein the first control unit controls the conveyor unit to halt the feed operation of the transfer medium from the feed tray to the printing unit when the detecting unit does not detect the second print command on the previous transfer medium within a predetermined time after detecting the first print command.
