摘要： According to one embodiment, a color erasing apparatus includes a color erasing section which erases a color of an image formed with an erasable color material on a sheet conveyed at first speed, a reading section which reads an image on the surface of the sheet conveyed at second speed higher than the first speed, a first conveying section, and a second conveying section. The first conveying section includes a first conveying roller arranged downstream in a sheet conveying direction of the color erasing section and conveys the sheet at the first speed. The second conveying section includes a second conveying roller arranged upstream in the sheet conveying direction of the reading section and in a position where the second conveying roller nips the conveyed sheet simultaneously with the first conveying roller. The second conveying section conveys the sheet to the reading section at the second speed.

摘要： A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit, and a controller. The decoloring unit decolors the image on the sheet conveyed through the sheet conveying unit. The decoloring unit is positioned downstream of the scanner in a sheet conveying direction. A distance along the sheet conveying direction between the scanner and the decoloring unit is shorter than a length of a first predetermined sheet size and longer than a length of a second predetermined sheet size. A controller determines whether the sheet conveyed by the sheet conveying unit is the first predetermined sheet size or the second predetermined sheet size. The controller performs a mode limiting process if the sheet size is determined to be the first predetermined sheet size.

摘要： A fixing unit includes a heater, a fixing member, a press roller, a sensor, a processor, and a memory. The fixing member is heated by heat generated by the heater. The press roller forms a nip portion through which a medium having a fixing target material transferred thereto passes, between the press roller and the fixing member. The sensor measures a temperature of the fixing member. The processor controls the temperature of the fixing member so as to be a target value by acquiring the temperature detected by the sensor in a first period, and also acquires the temperature detected by the sensor in a second period shorter than the first period. The memory records the temperature acquired in the second period.

摘要： An image forming apparatus includes first and second sheet storages, a sheet conveyer, an image reading unit configured to read a surface of a sheet conveyed from the first sheet storage by the sheet conveyer, an image forming unit configured to form an image on the sheet conveyed from the image reading unit, and a controller. The controller is configured to determine an amount of a color material appearing on the surface of the sheet based on image data generated by the image reading unit, determine one of the image forming unit and the second sheet storage as a sheet feeding destination, based on the determined amount of the color material and a threshold value that is associated with at least one of a type and content of an image to be formed on the sheet, and control the sheet conveyer to convey the sheet to the sheet feeding destination.

摘要： An image erasing apparatus according to an embodiment includes a sheet supply portion that supplies a sheet and an ejector. A first conveying path conveys the sheet from the sheet supply portion toward the ejector. A reader arranged on the first conveying path reads an image on the sheet. A second conveying path branches from the first conveying path at a downstream of the reader on the first conveying path and merges with the first conveying path at an upstream of the reader on the first conveying path. An erasing unit is arranged on the second conveying path. A conveying path changing portion is arranged at a branching portion. An operating portion receives a setup of the processing to the sheet. A controller changes a conveying path of the sheet in accordance with the setup received by the operating portion before the sheet is supplied from the sheet supply portion.

摘要： In accordance with an embodiment, an image forming apparatus encompasses a heat roller, a lamp, a use amount acquisition section, a switching controller and a cycle controller. The heat roller heats a sheet printed with a toner image. The lamp heats the heat roller. The use amount acquisition section acquires a use amount of the lamp. The switching controller repeats a processing from a moment at which the lamp is charged until the lamp is charged next after the lamp is not charged in a predetermined control cycle. The cycle controller sets the cycle based on the use amount.
