Abstract
According to an embodiment, an image erasing apparatus includes a reading unit, an erasing unit, an image forming unit, and a controller. The reading unit reads identification information formed on a sheet conveyed. The erasing unit erases a part or all of a first image formed on the sheet after the identification information is read. The controller obtains image data corresponding to the identification information that is read by the reading unit. The controller controls the image forming unit so as to form a second image, which is indicated by the obtained image data, onto the sheet from which the first image has been erased.
Claims20
An image forming apparatus comprising:
- a feeding unit which supplies a sheet to a conveyance path;
- a reading unit which scans the conveyed sheet to read a first region indicating a first image and a second region indicating identification information that identifies one of the sheet and a user;
- a storage unit which stores image data of a second image associated with the identification information;
- an erasing unit which decolors a part or all of the first image on the sheet conveyed on the conveyance path;
- an image forming unit which forms an image onto the sheet conveyed on the conveyance path after the erasing unit finishes the decoloring;
- and
- a controller which obtains from the storage unit the image data based on the identification information read by the reading unit, and controls the image forming unit to form, based on the obtained image data, the second image onto the first region of the sheet from which the part or all of the first image has been decolored.
An image forming method comprising:
- conveying a sheet to a conveyance path;
- scanning the conveyed sheet to read a first region indicating a first image and a second region indicating identification information that identifies one of the sheet and a user;
- decoloring a part or all of the first image on the sheet;
- obtaining image data of a second image associated with the read identification information;
- and
- based on the obtained image data, forming the second image onto the first region of the sheet from which the part or all of the first image has been decolored.
