1. An image-forming apparatus, comprising:
a controller;
a storage; and
a communicator, wherein
the controller
establishes a connection with a terminal device through the communicator using Quick User Datagram Protocol (UDP) Internet Connections (QUICs),
stores, in the storage, identification information for identifying the connection and key information to be used for encryption of transmission-reception information transmitted to and received from the terminal device,
communicates the transmission-reception information with the terminal device through Hypertext Transfer Protocol (HTTP)/3, and
establishes, when the connection with the terminal device is disconnected, a reconnection with the terminal device using the identification information to resume the communication of the transmission-reception information with the terminal device.
