摘要： An image forming apparatus includes the following. A conveying unit conveys a continuous sheet at least longer than a length of the apparatus itself. A first rotating member can be pressed to and separated from a second rotating member. The first rotating member can be rotated separated from the second rotating member. The continuous sheet can be stopped and held when the first rotating member is separated from the second rotating member. The image forming apparatus further includes a control unit. When the continuous sheet is stopped and held and the rotation of the first rotating member is started separated from the second rotating member, the control unit moves at least one of the first rotating member and the continuous sheet so that the continuous sheet is not in contact with the first rotating member, and then the control unit starts rotation of the first rotating member.

摘要： An image-forming apparatus forms an image on a roll sheet. A printer receives the roll sheet, forms the image thereon and ejects the image-formed roll sheet to a reel. A sheet position sensor, which is positioned near the printer, measures a position of the roll sheet along a width direction thereof. A control portion receives positional measurement data about the position of the roll sheet along the width direction thereof from the sheet position sensor and controls at least one of start time of image-forming operation in the printer and an image-writing position of the printer by settling at least one of the start time of image-forming operation and the image-writing position based on the positional measurement data.

摘要： An image forming apparatus includes: a conveyer that conveys continuous paper; an image creator that outputs an image onto the continuous paper, a heat source that imparts heat to the continuous paper; and a hardware processor that controls a printing action for forming an image on the continuous paper conveyed in a forward direction by the conveyer, using the image creator and the heat source, wherein when interrupting the printing action, the hardware processor performs withdrawal control in which the continuous paper is conveyed in a reverse direction such that a final image formed on the continuous paper before interruption of the printing action reaches a withdrawal position defined upstream of the heat source in the forward direction.

摘要： An image forming apparatus is connected to a paper processing apparatus and includes an image forming unit, a nip part and a hardware processor. The image forming unit performs image forming on continuous paper being conveyed on a conveyance path. The nip part nips the paper on the conveyance path. The processor selectively performs first control and second control according to an output timing of a conveyance control signal if the signal is output from the paper processing apparatus or the image forming apparatus. In the first control, the processor notifies the paper processing apparatus of permission to start or stop conveying the paper after causing the nip part to perform a press-and-contact operation or a separation operation. In the second control, the processor notifies the paper processing apparatus of the permission without causing the nip part to perform either operation.
