Abstract:
1. An image forming apparatus, comprising: a transport belt rotating around rollers that transports a sheet by attaching the sheet thereto by an electrostatic force; an image forming unit which forms an image on the sheet transported by the transport belt by ejecting ink droplets from a recording head onto the sheet; an duplex print unit which reverses the sheet, the first side of which has been printed, so as to form an image on the second side of the sheet; a carrying roller configured to transport the transport belt; and a first pushing roller disposed to face the carrying roller and configured to push the sheet to the transport belt, wherein the sheet is stopped so that a tip of the sheet is sandwiched between the first pushing roller and the transport belt, and wherein the apparatus stops the transportation of the sheet to the image forming unit after, the image is formed on the first side of the sheet and before the image is formed on the second side of the sheet until at least the tip of the second side of the sheet is not apart from the transport belt wherein the apparatus is configured to determine whether to stop the transportation of the sheet, the first side of which has been printed, to the image forming unit based on the information of the image to be printed on the first side of the sheet.
