Abstract
According to the embodiments, there is provided an image forming apparatus and an image erasing apparatus. The image forming apparatus forms, on a recording medium, an image showing the color material information about the erasing temperatures of a plurality of erasable color materials used for forming an image to be printed together with the image to be printed. The image erasing apparatus heats the plurality of erasable color materials to the highest erasing temperature or higher in the different erasing temperatures of the erasable color materials forming the image printed on the recording medium in order to erase the erasable color materials forming the image.
Claims10
An image forming apparatus that prints an erasable image on a recording medium, the image forming apparatus comprising:
- an image forming unit configured to form an image to be printed on a recording medium using a plurality of erasable color materials of which colors are erasable by being heated to a predetermined erasing temperature or higher and of which erasing temperatures are different;
- and
- a control unit configured to cause the image forming unit to form, together with the image to be printed, an image showing color material information about the erasing temperatures of the erasable color materials to be used on the recording medium.
An image erasing apparatus that erases an image printed on a recording medium using a plurality of erasable color materials of which colors are erasable by being heated to a predetermined erasing temperature or higher and of which erasing temperatures are different, the image erasing apparatus comprising:
- an erasing unit configured to erase the image by heating the plurality of erasable color materials;
- and
- a control unit configured to control a heating temperature of the erasing unit to be equal to or higher than a highest erasing temperature in the different erasing temperatures of the plurality of erasable color materials.
