## Abstract

According to an embodiment, an image erasing apparatus includes an erasing unit, an input unit, and a control unit. The erasing unit erases an image formed on a recording medium. The input unit inputs identification data which identifies an apparatus which forms the image on the recording medium. The control unit controls an operation of the erasing unit based on the identification data input by the input unit. According to another embodiment, an image forming apparatus includes an image forming unit which forms an image on a recording medium, the erasing unit, the input unit, and the control unit.

## Claims

### Claim 1

An image erasing apparatus, comprising:
an erasing unit configured to erase an image formed on a recording medium;
an input unit configured to input identification data for identifying an apparatus which forms the image on the recording medium; and
a control unit configured to control an operation of the erasing unit based on the identification data input by the input unit.

### Claim 2 (depends on 1)

The image erasing apparatus according to claim 1, wherein the input unit inputs data specific to the apparatus which forms an image on a recording medium as the identification data.

### Claim 3 (depends on 2)

The image erasing apparatus according to claim 2, wherein the input unit has a reading unit, the reading unit reads the image on the recording medium to obtain image data, and the control unit recognizes the identification data based on the image data.

### Claim 4 (depends on 1)

The image erasing apparatus according to claim 1, wherein the control unit determines whether the image is erasable based on the identification data.

### Claim 5 (depends on 1)

The image erasing apparatus according to claim 1, further comprising:
a control table which stores data specific to a plurality of image forming apparatuses and control data for controlling the erasing operation of the erasing unit so as to be associated with the specific data,
Wherein the control unit operates the erasing unit based on the control data corresponding to the specific data corresponding to the identification data.

### Claim 6

An image forming apparatus, comprising:
an image forming unit configured to form an image on a recording medium;
an erasing unit configured to erase an image formed on a recording medium;
an input unit configured to input identification data which identifies an apparatus which forms the image on a recording medium from which an image is erased; and
a control unit configured to control an operation of the erasing unit based on the identification data input by the input unit.

### Claim 7 (depends on 6)

The image forming apparatus according to claim 6, wherein the input unit inputs data specific to the apparatus which forms the image on the recording medium as the identification data.

### Claim 8 (depends on 6)

The image forming apparatus according to claim 6, wherein the input unit has a reading unit, the reading unit reads the image on the recording medium to obtain image data, and the control unit recognizes the identification data based on the image data.

### Claim 9 (depends on 6)

The image forming apparatus according to claim 6, further comprising:
a control table which stores data specific to a plurality of image forming apparatuses and control data for controlling the erasing operation of the erasing unit so as to be associated with the specific data,
Wherein the control unit operates the erasing unit based on the control data corresponding to the specific data as the identification data.

### Claim 10 (depends on 6)

The image forming apparatus according to claim 6, further comprising:
a conveyance unit which conveys, to the image forming unit, the recording medium from which the image is erased by the erasing unit.
