An image processing apparatus includes: a processing unit that executes a process related to an image; an acquisition unit that acquires a first key and a second key including a restriction condition; a transition unit that transitions from a first operation mode to a second operation mode when the first key is acquired; a counting unit that counts usage of the processing unit; and a restricting unit that restricts execution of the process by the processing unit in the second operation mode according to a relationship between the counted usage and the restriction condition included in the acquired second key.
