An image forming apparatus includes a belt, a cleaning member, a backup member, a pressing-force changing mechanism, and a control unit. The method operates by defining a work time for the Requestor and each of the one or more Invitees and calculating an international meeting time within the work time of the Requestor and each of the one or more Invitees. The apparatus includes a hopper feeder attachment, which is self-adjusting during pellet jams. Presence indicators stored in the telephone are dynamically updated via the packet network connection and are used as part of the telephone number selection algorithm. Of course, many modifications, variations, and alternatives are possible without departing from this embodiment.
