According to one embodiment, first and second branch paths of a decoloring apparatus are formed downstream in a sheet conveying direction of a reading section in a conveying path. A diverting section is provided at a branch point of the first and second branch paths in the conveying path. A control section determines on the basis of image data whether decoloring processing should be applied to a sheet, diverts, if determining that the decoloring processing should be applied to the sheet, the sheet to the first branch path with the diverting section, and diverts, if determining that the decoloring processing should not be applied to the sheet, the sheet to the second branch path with the diverting section. A decoloring section is provided between the reading section and the branch point in the conveying path and heats the sheet to decolor an image formed with a decolorable color material.

According to one embodiment of the present invention, an erasing apparatus includes a used sheet stacking tray, an image erasing unit, a stand-by tray, a stand-by tray driving unit, and an erased sheet stacking tray. The used sheet stacking tray stacks thereon a used sheet on which an image is formed using an erasable colorant of which a color is erased by a predetermined heating process. The image erasing unit performs the heating for the used sheet which is received one by one from the used sheet stacking tray and discharges an erased sheet from which the image formed on the used sheet is erased. The stand-by tray has a mechanism which can be driven in a predetermined direction and places thereon the erased sheet discharged by the image erasing unit. The stand-by tray driving unit drives the stand-by tray and enables the erased sheet to free-drop. The erased sheet stacking tray is disposed under the stand-by tray and stacks thereon the erased sheet which free-drops from the stand-by tray.

In general, in a sheet feeding device of embodiments, a shaft connects through an one-way clutch structure to a conveying roller, rotates in a first direction and a second direction opposite to the first direction, transmits the torque to the conveying roller to cause the conveying roller to rotate in the first direction if the shaft rotates in the first direction. The shaft does not transmit the torque to the conveying roller if the shaft rotates in the second direction. The shaft limits the rotation of the conveying roller in the second direction while the shaft is in a rotation-stop state. A controller has a second mode in which the shaft is rotated in a second direction to allow rotation of the conveying roller in the second direction.
