An authentication unit of a digital MFP carries out communication with an authentication server and executes an authentication procedure. The authentication unit acquires authentication information from an operator, transmits an authentication request including the authentication information to the authentication server, and receives an authentication result from the authentication server. A determination unit determines whether or not to permit offering of a function called by an operation performed on an operation unit. A flash memory stores a network authentication setting designating necessity or non-necessity of the authentication procedure for each function in a manner that the network authentication setting may be edited. When a function designated in the network authentication setting as a function requiring the authentication procedure is called, the authentication unit executes the authentication procedure. After the authentication succeeds, the determination unit permits to offer the called function.
