    摘要： An image forming apparatus/method transports a sheet to an image forming unit that can form images on both sheet sides. The sheet is fed to the image forming unit at a predetermined image formation start timing for the first side image formation, thereafter is reversed, and re-fed to the image forming unit for the second side image formation while the first side image-formed sheet waits at least one of sheet waiting positions. A full state, where all the sheet waiting positions are full of the first side image-formed sheets, is detected. The number of sheets transported is controlled so that it is greater than the number of the sheet waiting positions. When the full state is detected, the sheet re-feeding is controlled so that a head sheet among the first side image-formed sheets waiting at the sheet waiting positions is fed in advance of the predetermined image formation start timing.

    摘要： An image forming apparatus capable of reducing damage in a fixing section and printing a high-quality image on a sheet at low cost without reducing productivity. A sheet shifting mechanism is arranged upstream of a transfer roller and moves the sheet in a sheet lateral direction orthogonal to the sheet conveying direction. In order to change a position at which a sheet passes through a fixing roller, the sheet shifting mechanism is controlled for every conveyance of a predetermined number of sheets, whereby sheet movement in the sheet lateral direction is controlled. A correction amount for an error due to sheet shifting by the sheet shifting mechanism is stored for each of sheet shift positions. An image forming position in the sheet lateral direction of a photosensitive drum is shifted on the basis of the sheet shift position and the stored correction amount.

    摘要： An image forming apparatus which conveys waste toner includes a buffer portion 101 capable of temporarily containing the waste toner and a waste toner container 102 capable of containing the waste toner and a waste toner container 102 capable of containing the waste toner. The waste toner is dominantly contained in the waste toner container 102 compared with the buffer portion 101. When the waste toner container 102 is filled with the waste toner, the waste toner can be contained in the buffer portion 101. An engine controller 120 detects whether the buffer portion 101 is filled with the waste toner 112 or not through a buffer portion waste toner full state detection sensor 105. When the buffer portion 101 is filled with the waste toner 112, the engine controller controls so that a conveyance operation by a first waste toner pipe 103 and an image forming operation are stopped.
