Abstract
An erasing apparatus includes a conveyance path configured to convey a sheet on which an image is formed with a coloring agent which is erased by heating. A first erasing unit is disposed on the conveyance path and is configured to heat the sheet when the sheet is conveyed between a first heating component and a first press component. A second erasing unit is disposed on the conveyance path downstream from the first erasing unit and is configured to heat the sheet when the sheet is conveyed between a second heating component and a second press component. A control section is configured to control a temperature of the first heating component at a first temperature at which the image on the sheet can be erased and to control a temperature of the second heating component at a second temperature lower than the first temperature.
