摘要:
On the basis of information of a topology map, a parent node ID list is generated to show correspondence of ID of each node to that of its parent node. Information given by the parent node ID list is transmitted as connection display data in a predetermined format. The receiving side, on the basis of the received connection display data, obtains information of a connecting status display to display connecting status of a network. On the basis of this information, a display to show connecting status of the network is displayed.

A fixing device is provided in which a rotation member and a roller are caused to rotate pressing against each other, a recording paper is sandwiched and transported in a nip region between the rotation member and the roller, a leading edge of a peeling plate is positioned with respect to a peripheral surface of the rotation member, and the recording paper is separated from the rotation member by the peeling plate. In this fixing device, a surface of the peeling plate faces a transport route of the recording paper. Furthermore, in this fixing device, a contact member is provided that contacts a rear surface of the peeling plate displaced in a direction in which the leading edge of the peeling plate approaches the peripheral surface of the rotation member and prohibits displacement of the peeling plate after contact of the peeling plate to the contact member.
