An operation panel of an image forming apparatus receives in a login state and does not receive in a logout state a job setting instruction, etc. When a communication section receives a confirmation request to confirm use status of the image forming apparatus, a controller of the image forming apparatus specifies a requester who is a user of a communication device having transmitted the confirmation request and determines whether the image forming apparatus is to be set in a reserved state based on communication with the communication device. When a user information set of the requester is input in a state in which the image forming apparatus is in the reserved state, the controller causes the operation panel to transition from the logout state to the login state. The controller refuses additional login from a user other than the requester during the image forming apparatus being in the reserved state.
