摘要： An image forming apparatus with a duplex printing function may include a closeable and openable portion. In one example, the portion may correspond to a cover of the image forming apparatus. The cover may include guiding portions configured to define a return path for duplex printing. In another example, the portion may correspond to a document reading unit including an outer casing. A portion of the outer casing may be configured to guide a recording sheet that is conveyed out of a housing of the image forming apparatus by a switchback roller. In one example, the switchback roller may convey a recording sheet to a position above an upper surface of the outer casing.

摘要： An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.

摘要： An acquisition unit acquires output data including first image data including first clear toner plane data and second image data including color plane data and second clear toner plane data. When the output data includes the first image data, a first output unit outputs first print data including first identification information representing an instruction to form an image on a first recording medium to which clear toner has not been applied to an image forming unit. When the output image includes the first image data and the second image data, a second output unit outputs second print data including second identification information representing an image formation instruction for a second recording medium to which the clear toner has been applied. When the output data does not include the first image data but includes the second image data, the second output unit outputs third print data including the first identification information.

摘要： An image forming apparatus includes an apparatus body, an image forming unit, and a retransporting unit. The retransporting unit includes a transporting roller for applying a transporting force to the sheet and an input portion disposed at a position shifted upstream of the transporting roller in a retransporting direction. The input portion is configured to receive an input of a drive force supplied from the apparatus body. The retransporting unit further includes a drive shaft extending in a retransporting direction. The drive shaft is configured to transmit the drive force from the input portion toward the transporting roller by rotating about an axis thereof. A height of the image forming apparatus may be reduced by this configuration.

摘要： An image forming apparatus is provided. The image forming apparatus includes an image forming unit, a return-sheet conveyer unit to convey a recording sheet carried from the image forming unit along a return-sheet path to return to the image forming unit, an upper frame unit including a pair of side frames to support the image forming unit in a position there-between, and a pair of lower frames arranged to have a predetermined amount of clearance there-between to have the return-sheet conveyer unit in the clearance, and configured to be less rigid than the upper frame unit and to support lower sections of the pair of side frames. A vertical position of the return-sheet conveyer unit with respect to the image forming unit is defined with reference to the upper frame unit by having a part of the return-sheet conveyer unit aligned to be in contact with the upper frame unit.

摘要： When an image is formed on a second side of a sheet, the image forming position is adjusted on the basis of a value calculated using the amount αn of lateral registration deviation detected before forming an image on the first side and the amount γn-1, of lateral registration deviation of the previous sheet on which image formation is performed. Thus, it is possible to adjust the positions of irradiation of laser light to the photosensitive drums and to start forming the second-side images as soon as the first-side images have been primary-transferred onto the intermediate transfer belt.
