Abstract: An image forming apparatus that transfers an image from an image carrier onto a sheet passing between the image carrier rotating and a transfer member includes a fixing unit configured to thermally fix the image on the sheet while nipping and conveying the sheet with a pair of fixing members after the transfer, at least one of the fixing members rotating; a measuring unit configured to measure surface movement speed of the sheet in a non-contact manner while the sheet is being conveyed by the fixing members; and a control unit configured to control rotation speed of the fixing members in accordance with a result of the measurement, to adjust speed of conveyance of the sheet to a target speed determined beforehand for peripheral speed of the image carrier, the control being performed while the sheet being conveyed is in contact with the transfer member and the fixing members.

Abstract: A photographing system includes a photographing device configured to photograph a surface; a detector configured to detect a change in a position of an object in a space between the surface and the photographing device; and an obtaining portion configured to obtain an image of an area of the surface by the photographing device when the detector detects the change, the area being not viewed by the photographing device before the change due to interruption of the object and being viewed by the photographing device after the change.

Abstract: Provided is an image forming apparatus including: a heater heating a fixing member; an acquisition unit acquiring, when an image for one page includes a coded identifier image, information on a range of formation of the coded identifier image on a recording sheet in a sheet-passing direction; a target temperature switching unit switching a target temperature at which temperature of the fixing member is to be maintained at least between a first fixing temperature and a second fixing temperature higher than the first fixing temperature; a controller controlling the heater so that the temperature of the fixing member is maintained at the target temperature, wherein the target temperature switching unit switches the target temperature at a timing such that the temperature of the fixing member is equal to the second fixing temperature while a toner image in the range of formation of the coded identifier image is being fixed.

Abstract: A fixing device includes an excitation coil, a fixing member heated by electromagnetic induction by the excitation coil, a magnetic shunt alloy member, a Curie temperature of which is higher than a target fixing temperature, a determiner that determines whether the temperature of a non-sheet passing region of the fixing member is about to reach the Curie temperature, and a power controller that controls power supplied to the excitation coil. Until the determiner determines that the Curie temperature is about to be reached, the power controller performs feedback control to provide power to the excitation coil. When the determiner determines that the Curie temperature is about to be reached, the power controller switches to fixed power control so that a difference between power supplied when the Curie temperature is about to be reached and power supplied after reaching the Curie temperature falls within an allowable range.

Abstract: Attachment of a USB memory is sensed and whether the USB memory can be recognized or not is determined based on data information output from the USB memory. When the USB memory cannot be recognized, an emulation transition screen is displayed. Thereafter, when an instruction to start transition to an emulation mode is given, an emulation mode transition instruction signal and an IP address of an MFP on a network are output. Receiving the input of the emulation mode transition instruction signal, an emulation mode start-up/end unit starts up the emulation mode.

Abstract: A charging management server is informed of an ID number stored in an IC card, and a user charging table of the charging management server is read. A new user charging list is transmitted to an MFP. In the case where the MFP receives a cooperative job to be executed by a cooperative server, a sub charging list is generated. The generated new sub charging list is transmitted together with image data to the cooperative server. The cooperative server executes the job on the basis of charging a fee for the job. As the job is executed on the basis of charging, the sub charging list is updated. In parallel with the execution of the cooperative job by the cooperative server, the MFP can perform a normal job according to the charging list.

Abstract: Whether a job execution instruction has been issued or not is determined. When it is determined that the job execution instruction has been issued, a job ID is issued. Contents of the job in accordance with the job execution instruction are checked. Then, whether the job is a Scan to USB memory job in an emulation mode or not is determined. When it is determined that the job is the Scan to USB memory job in the emulation mode, a sub job ID brought in correspondence with the issued job ID is issued.

Abstract: An authentication printing function is performed in a multi function peripheral (MFP). A user transmits a job from a PC to the MFP, and then performs card authentication by bringing cards close to an authentication device. Authenticated-user information is transmitted to the MFP, where the authenticated users are registered. A print job is generated, and a billing scenario is generated in which a charge is allocated among the plurality of authenticated users on the basis of a billing pattern. When the billing scenario is approved by the user, the job is executed, and the authenticated users are each billed for the charge allocated thereto on a per-page or per-set basis, in accordance with the billing scenario. Accordingly, a billing device for an image processing device which can allocate a charge among a plurality of users without the need of complicated operations is provided.
