  • Patent number: 10737893
    Abstract: 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.

  • Publication number: 20200207138
    Abstract: 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.

  • Patent number: 10698348
    Abstract: An image forming apparatus includes a heater and a controller. The heater includes a plurality of heater elements arranged in a main scanning direction to fix an image on a sheet passing a nip. The controller is configured to determine image-forming regions and non-image-forming regions among sheet regions of the sheet divided in the main scanning direction and a sub-scanning direction based on image data of the image. The controller is further configured to determine, as heating regions, the image-forming regions and a first part of the non-image-forming regions satisfying a predetermined condition, and determine, as non-heating regions, a second part of the non-image-forming regions not satisfying the predetermined condition. The controller is configured to energize one or more of the heater elements corresponding to the heating regions, selectively at timing when the heating regions pass the nip.

  • Publication number: 20200064761
    Abstract: According to an embodiment, a fixing device 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.

  • Patent number: 10336117
    Abstract: 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.
