There is described a management system which makes it possible to appropriately manage the managed apparatus, while securely maintaining the productivity of the managed apparatus. The system includes the management apparatus, the managed apparatus and the HTTP server. The managed apparatus is provided with a connection controlling section that periodically connects the managed apparatus itself to the HTTP server at a regular connecting timing, so as to read information sent from the management apparatus and to write apparatus information into the HTTP server. The connection controlling section determines whether or not the managed apparatus is coupled to the HTTP server at the regular connecting timing, based on its loading status and/or a presence or absence of the current job and connects it to the HTTP server asynchronously with the regular connecting timing, when determining that the managed apparatus is not coupled to the HTTP server at the regular connecting timing.
