Abstract: The image forming apparatus transfers an image onto a surface of a sheet at a transfer position on a conveying path. A pair of conveying rollers convey the sheet to the transfer position. The image sensor reads the sheet upstream of the transfer position. The rotary body is disposed to face the image sensor with the conveying path interposed therebetween. The rotary body includes a background portion configured to face a reading surface of the image sensor when the rotary body is at a first rotational position, and a cleaning portion configured to come into contact with the reading surface of the image sensor when the rotary body is at a second rotational position.

Abstract: A sheet sorting device according to an embodiment includes a transporting unit that transports a sheet. A reading unit generates an image of a surface of the sheet. A decoloring unit performs a decoloring processing to decolor an image on the sheet. The sheet sorting device includes a plurality of sheet stacking trays. A processor causes the reading unit to generate an image of the surface of the sheet after the decoloring unit performs the decoloring processing on the sheet. The processor determines a color of the sheet based on the generated image. The processor determines one sheet stacking tray out of the plurality of sheet stacking trays as a transport destination of the sheet, based on the determined color. The transporting unit transports the sheet to the determined sheet stacking tray.

Abstract: Methods (300, 1000) of determining a light scattering property of a medium (152), are disclosed. The medium (152) is illuminated through a test pattern (e.g., 155, 510), the test pattern (155, 510) comprising at least one region containing a first pattern with substantial variation in two orthogonal directions at one scale. The test pattern (300, 1000) further comprises at least one other region containing the first pattern at a different scale. The light reflected from the illuminated medium (152) through the test pattern is measured to capture an image of the illuminated medium. A light scattering property of the medium (152) is determined based on the measured light.

Abstract: A fixing member having an outer peripheral surface brought in pressure contact with a sheet, an induction coil along the member, and a high frequency power source section that heats the heat generating layer of the fixing member by supplying an alternating current to the induction coil. A magnetic flux regulating section that restricts the generation of heat in a specified region of the fixing member in the widthwise direction of the sheet is provided. Image regions occupied by the image to be fixed are detected in the widthwise direction of the sheet. Control of specifying the region in which the generation of heat should be restricted for the magnetic flux regulating section is executed so that only regions corresponding to the image regions of the fixing member are substantially heated in the widthwise direction of the sheet, sheet-by-sheet according to the result of detection.
