The communication system according to the present invention is made up of: a connected communication terminal () to which communication is requested; a connecting communication terminal () that requests a communication with the connected communication terminal (); a session management server () that manages sessions between the communication terminals; a trigger server () that transmits, to the connected communication server (), the request made by the session management server (); and routers (and) that relay between the connecting communication terminal () and the connected communication terminal (), and a network (). In the system, the connected communication terminal () holds a permission list (L) that is a list of communication terminals to which connection is permitted, and the session management server () judges, with reference to the permission list (L), whether or not the communication between the connected communication terminal () and the connecting communication terminal () is permitted.

An image forming apparatus has a toner carrier and a toner passing control having a plurality of toner passing holes for controlling passage of a toner. The toner passing control has upstream side secured, the downstream side extended by a spring, and is contacted with a stay on the downstream side of the contact point with the toner carrier, so that corrugation deformation is prevented. A vibrating plate and an ultrasonic vibration generator are coupled through a coupling portion, thereby relative displacement between the vibrating plate and the ultrasonic vibration generator is allowed. A detachable toner cartridge is formed by integrating a developing roller and a toner storing container.
