Abstract
In accordance with an embodiment, an image decoloring apparatus comprises a conveyance path configured to convey a sheet on which an image is formed with a coloring agent that is decolored by heat; a first heat roller configured to be arranged at the upstream side of the conveyance path; and a second heat roller configured to be arranged at the downstream side of the conveyance path. Each of the first heat roller and the second heat roller includes a cylindrical portion and a heat source. The thickness of the cylindrical portion constituting the first heat roller is larger than the thickness of the cylindrical portion constituting the second heat roller. In this way, the heat capacity of the first heat roller is also larger than the heat capacity of the second heat roller.
