ABSTRACT:
An image forming apparatus has an erasing device therein which automatically erases an image formed on a sheet by a recording agent implemented by a decolorizable coloring agent, e.g., toner. The erasing device emits light having a wavelength range of 820 nm or so while generating heat and may be constituted by a halogen lamp. As a result, the sheet is regenerated and can be repetitively used.
