Abstract
An image forming apparatus includes a first connection portion, a second connection portion, a communication processing portion, a switch processing portion, and a connection determination processing portion. To the switch processing portion, the first connection portion and the second connection portion are connected in parallel. The switch processing portion breaks a communication path between the second connection portion and the switch processing portion when the facsimile communication process is executed by the communication processing portion. The connection determination processing portion, when a predetermined determination start condition is satisfied, causes the switch processing portion to break the communication path, and then when a predetermined line voltage is applied to the switch processing portion, determines that a connection between the first connection portion and the public switched telephone network is normal.
