In accordance with one embodiment, a color erasing apparatus comprises a conveyance path, a color erasing section and a control section. The conveyance path conveys a sheet. The color erasing section erases the color of an image formed with color erasable recording agent serving as recording agent containing coloring agent the color of which can be erased by heating. The control section carries out a control, in a case where the image formed on the sheet is not an image formed with the color erasable recording agent, so that the sheet is not subjected to a color erasing processing by the color erasing section.

A reading device includes a conveyance control section for controlling document conveyance. In a case of double-sided reading of a document and with a cutout document mode applied, the conveyance control section stops a pair of reverse-rotation rollers at a time point when the document has been conveyed to a distance resulting from adding an additional distance, which is predetermined or determined based on a recognized cutout width in the document conveyance direction, to a reference distance since a time point of passage of a rear end of a document-detecting detection part, and thereafter start reverse rotation of the pair of reverse-rotation rollers.

A recording medium processing apparatus includes an apparatus body; plural transport paths that are provided in the apparatus body and radially extend from a predetermined place and along which a transported recording medium passes; and plural opening and closing members that are openable and closable with respect to the apparatus body and are disposed so that positions thereof in a circumferential direction of the plural transport paths that are arranged radially are different.

According to an embodiment, an image elimination apparatus eliminates an image formed on a sheet. A sheet supply unit supplies the sheet on which the image is formed. A first reader reads the sheet supplied by the sheet supply unit. An image eliminator eliminates the image formed on the supplied sheet. A second reader reads the sheet passing through the image eliminator. A discharge unit stacks the sheet to be discharged. A controller causes the first reader to read the sheet at a first speed in order to judge whether the sheet is reusable or not based on the reading result of the first reader. The controller also causes the second reader to read the sheet at a second speed faster than the first speed in order to judge whether the image formed on the sheet has been eliminated or not based on the reading result of the second reader.

In a case where a job for executing both one-sided printing and two-sided printing is received, printing is controlled based on whether or not a predetermined type of sheets in which there is an order between the sheets are used for the received job whereby productivity is improved in a case where the predetermined type of sheets are not used for the received job, and a mismatch between content of a page and an order of the sheets does not occur in a case where the predetermined type of sheets is used for the received job.

In accordance with one embodiment, a color erasing apparatus comprises a conveyance path, a color erasing section and a control section. The conveyance path conveys a sheet. The color erasing section erases the color of an image formed with color erasable recording agent serving as recording agent containing coloring agent the color of which can be erased by heating. The control section carries out a control, in a case where the image formed on the sheet is not an image formed with the color erasable recording agent, so that the sheet is not subjected to a color erasing processing by the color erasing section.

A reading apparatus includes a reading unit that reads a document, a transport path, an output path for outputting the document read by the reading unit, a display unit that displays a setup screen, and a control unit configured to control the reading unit and the display unit. The output path includes a first output path and a second output path that separately lead to different document output destinations, and the output path is formed such that a use path used to output the document is changed between the first output path and the second output path. The control unit is configured to obtain path information indicating the use path and a reading setup. The control unit is configured to, based on the reading setup and the path information, cause the display unit to display a suggestion indication suggesting changing the reading setup or suggesting changing the use path.

Temperature of a printing medium 110 is sufficiently decreased by stopping the printing medium 110 in a discharge path, conveying the printing medium at a low speed, switching a conveyance path, or the like. If the temperature of the printing medium 110 can be sufficiently decreased, the thermochromism phenomenon is suppressed. As a result, it is possible to provide an image forming apparatus capable of achieving highly accurate color matching and color stability.

An image forming apparatus includes an image forming portion, a reverse roller pair, a revering motor. A controller controls rotation of the reverse motor in a first feeding mode for the sheet with a first length and in a second feeding mode for the sheet with a second length shorter than the first length. The controller executes a first acceleration control in which the reverse motor rotating in the first rotational direction is accelerated from a predetermined speed to a first target speed faster than the predetermined speed after a rear end of the sheet passes through the image forming portion in the first feeding mode, and said controller executes a second acceleration control in which the reverse motor rotating in the first rotational direction is accelerated to a second target speed slower than the first target speed after the rear end of the sheet passes through the image forming portion in the second feeding mode.

An image reading device includes a conveyance unit configured to convey a carrier sheet and a reading object, a reading unit configured to read an image of the reading object, a display unit configured to receive an input of information about whether the reading object is conveyed using the carrier sheet, and a control unit configured to determine whether the reading object is being conveyed using the carrier sheet. The control unit performs predetermined processing on the image read by the reading unit when it is determined that the reading object is being conveyed using the carrier sheet. The control unit does not perform the predetermined processing on the image read by the reading unit when it is determined that the reading object is being conveyed without using the carrier sheet.
