In an image forming apparatus service system, each image forming apparatus adds, when an abnormal or preabnormal phenomenon or similar factor to be reported occurs therein, information relating to its operation and including the cumulative number of images formed to information representative of the above factor. The information and additional information are sent to a central control unit managing the image forming apparatus. Each central control unit collects and stores the information received from image forming apparatuses lying in its coverage apparatus by apparatus and transfers the day's (one day) information stored to a server at a preselected time via a WAN (Wide Area Network). The server stores the information received from all the central control units in a format suitable for a data base. A person using each data processing unit is capable of downloading desired information from each central control unit or the server via the WAN by operating a keyboard or a mouse.
