An Internet facsimile apparatus makes inquiry about capability, which a destination possesses, to a local server. The server is connected to the same LAN as that of the Internet facsimile apparatus. When the local server has no capability information of the destination, the Internet facsimile apparatus makes inquiry to a DNS server and obtains capability information. Then, the Internet facsimile apparatus makes an image to be suitable for the capability of the destination and transmits it to the destination via the Internet. As a result, the Internet facsimile apparatus on a transmitter side can surely obtain capability information of a destination terminal, thereby making it possible to carry out the same capability exchange as that of G3 facsimile apparatus.
