When an ID card (41, 81) including user ID stored therein is set in an image processing apparatus (1, 71), the user ID is read out of the IC card. Upon depression of a key instructing individual setting, ID information including the user ID and apparatus ID is transmitted to a computer terminal (3; 3-1, 3-2) which stores a plurality of user ID's and setting information corresponding to the apparatus. Responding to the ID information transmitted, the computer terminal transmits individual setting information stored therein for each user back to the image processing apparatus, whereupon the apparatus stores the individual setting information in a memory and realizes the individual setting for each user, which corresponds to the set user ID, in a control panel (8) of the apparatus.
