An image forming apparatus determines whether crease processing at a plurality of portions set on the sheet includes crease processing on two, front and back surfaces of the sheet; determines, if it is determined that crease processing includes crease processing on the two surfaces of the sheet, whether a connected post-processing apparatus that performs crease processing on a sheet can perform crease processing on the two, front and back surfaces of the sheet by one feeding; and controls, if it is determined that the connected post-processing apparatus cannot perform crease processing on the two surfaces by one feeding, to change, to one of the front and back surfaces of the sheet based on attribute information of the sheet, a surface to be processed in crease processing at the plurality of portions.

An image forming apparatus including an image forming unit, first and second discharging portions, first and second supporting portions, an image reading portion, and first and second switching portions is provided. The first switching portion switches between causing a sheet bearing an image formed by the image forming unit to be discharged to the first supporting portion by the first discharging portion and causing the sheet to be conveyed toward the image reading portion that reads the image. The second switching portion switches between causing the sheet whose image has been read to be conveyed toward the second discharging portion that discharges the sheet whose image has been read to the second supporting portion and causing the sheet to be conveyed toward the image forming unit. The image reading portion is disposed above the first discharging portion and further on the inside of the apparatus than the second switching portion.

A printing apparatus includes a printing head that prints on a printing medium, a moving member that moves reciprocally with the printing head, and a conveying member that conveys the printing medium in a direction which intersects a printing head moving direction. Also included are a module contained in a contained position in a non-printing period, and developed in a developed position in a printing period, and a drive connection member that moves the module between the contained and developed positions with conveying member drive. The drive connection member includes a trigger arm that enters a printing head moving area when the moving member is driven in a direction opposite to which the printing medium is conveyed. When the moving member presses and moves the trigger arm, the conveying member is connected to the module such that a connected state in which the driving force transmission is maintained.

To provide a transfer apparatus correcting a curl of a card efficiently while preventing the card from deteriorating, a printing apparatus includes a transfer section transferring a transfer surface of a transfer film to the card, a rotating unit reversing the front side and back side of the card in two-sided transfer, a decurl mechanism correcting a curl of the card with the transfer surface transferred in the transfer section, and a control section controlling the decurl mechanism. The control section controls the decurl mechanism such that a correction amount for the card with the transfer surface transferred to one surface in two-sided transfer is smaller than a correction amount for the card in one-sided transfer, and that the total sum of correction amounts for respective surfaces of the card in two-sided transfer is smaller than the correction amount for the card in one-sided transfer.

A first feeding unit is configured that is provided in a first printing unit that includes a first recording unit that executes a recording operation for a long strip-like recording medium pulled out from a first holding unit that holds the recording medium in a wound state. The first feeding unit further includes a pair of feeding rollers that sort the recording medium discharged from the first printing unit, to the side of a second printing unit stacked on the first printing unit or to the side opposite to that of the second printing unit. The first feeding unit temporarily accommodates the sorted recording medium and thereafter, feeds the recording medium to a guide path, and sorts the recording medium fed by the pair of feeding rollers, to the side of the second printing unit using a sorting part.

A controller in a one-side printing mode moves movable rollers to form a one-side printing route and moves a second head unit so that the second head unit faces a front side of a web. The controller then controls a first head unit and a second head unit to print images of respective pages on the front side of the web while transferring the web at a transfer speed twice as fast as that in a both-side printing mode.
