Abstract
Provided are an image erasing apparatus which erases an image printed on a sheet and an image forming apparatus having an image erasing function. The image erasing apparatus and the image forming apparatus each include a readout unit, an erasing unit, and a control unit. The control unit acquires authentication information of a user who uses the apparatuses and allows the erasing unit to erase the image when determining that the acquired authentication information coincides with authentication information read out by the readout unit.

An image erasing apparatus which erases an image printed on a sheet, comprising:
- a readout unit configured to read out authentication information of a user who prints the image, the authentication information of the user being contained in the image printed on the sheet;
- an erasing unit configured to erase the image printed on the sheet;
- and
- a control unit configured to acquire authentication information of a user who uses the apparatus and determines whether the acquired authentication information coincides with the read out authentication information to allow the erasing unit to erase the image when determining that the acquired authentication information coincides with the read out authentication information.
An image forming apparatus having an image erasing function of erasing an image printed on a sheet, comprising:
- an image forming unit which prints an image containing authentication information of a user, who prints the image, on a sheet;
- a readout unit which reads out the authentication information of the user who prints the image, the authentication information of the user being contained in the image printed on the sheet;
- an erasing unit which erases the image printed on the sheet;
- and
- a control unit which acquires authentication information of a user who uses the apparatus and determines whether the acquired authentication information coincides with the readout authentication information to allow the erasing unit to erase the image when determining that the acquired authentication information coincides with the read out authentication information.
