An erasable image forming material includes a color former, a developer, a binder resin, and a polymer decolorizer having an electron donating group capable of physically or chemically adsorbing the developer. This polymer decolorizer is, e.g., a polymer compound having a sugar skeleton, representatively starch. This image forming material can form sharp images and erase images by heat or a solvent to achieve a good erased state.
