## Abstract

An image forming apparatus includes: a wireless communication board on which a communication circuit is mounted, the communication circuit communicating image data with an external device in a wireless manner; an image forming unit that forms an image based on the image data; a control board connected to the wireless communication board via a connection line to control an image forming operation of the image forming unit; and an accommodation portion of a metal material in which the control board is accommodated, wherein a predetermined metal plate constituting the accommodation portion has a recessed portion, and the wireless communication board is positioned in the recessed portion.

## Claims

### Claim 1

An image forming apparatus comprising:
a wireless communication board including a communication circuit configured to communicate image data with an external device wirelessly;
an image forming unit configured to form an image based on the image data;
a control board connected to the wireless communication board via a connection line, and configured to control an image forming operation of the image forming unit;
a metal accommodation portion accommodating the control board and including a predetermined metal plate with a recessed portion, wherein:
the predetermined metal plate includes an attachment portion formed by cutting and raising the predetermined metal plate to attach the wireless communication board; and
the wireless communication board is disposed in the recessed portion of the predetermined metal plate; and
a sheet attached to the predetermined metal plate to cover a hole formed in the predetermined metal plate to form the attachment portion.

### Claim 2 (depends on 1)

The image forming apparatus according to claim 1, wherein the sheet is attached onto a surface of the predetermined metal plate facing the control board.

### Claim 3 (depends on 1)

The image forming apparatus according to claim 1, wherein the sheet includes a magnetic layer containing metal powder.

### Claim 4 (depends on 3)

The image forming apparatus according to claim 3, wherein the sheet includes a protective layer configured to protect the magnetic layer, and an adhesive layer configured to attach the sheet to the predetermined metal plate, in addition to the magnetic layer.

### Claim 5 (depends on 1)

The image forming apparatus according to claim 1, further comprising another sheet between the predetermined metal plate and the wireless communication board.

### Claim 6 (depends on 5)

The image forming apparatus according to claim 5, wherein the another sheet includes a magnetic layer containing metal powder.

### Claim 7 (depends on 5)

The image forming apparatus according to claim 5, wherein the another sheet is attached to the predetermined metal plate to cover an antenna region of the wireless communication board.
