An image forming apparatus includes a first wireless communication unit that receives data from a mobile phone, and a reader-writer that transmits an address of the first wireless communication unit to the mobile phone. The mobile phone includes a contact/non-contact IC card that receives the address, and a second wireless communication unit that transmits image data to the first wireless communication unit utilizing the address. When communication is made between the mobile phone and the image forming apparatus, the address of the first wireless communication unit is transmitted to the contact/non-contact IC card through the reader-writer, and the second wireless communication unit transmits data to the first wireless communication unit utilizing the address.
