An electronic apparatus operated by a remote operation device includes a log-in managing part and a display controlling part. When log-in operation inputting log-in information is carried out, if a log-in user to the electronic apparatus does not exist, the log-in managing part logs-in the user to the electronic apparatus. When log-out operation logging-out the user from the electronic apparatus is carried out, the log-in managing part logs-out the user from the electronic apparatus. If the log-in managing part logs-out the user from the electronic apparatus, the display controlling part displays a re-login key for re-login of a log-out user on the remote operation device without inputting the log-in information. If operation of the re-login key is carried out, the log-in managing part logs-in the log-out user to the electronic apparatus by using the log-in information used when the log-out user is precedingly logged-in to the electronic apparatus.
