摘要： An image forming apparatus has a charging member opposed to an outer circumferential surface of a rotating object to be charged. The image forming apparatus has a voltage applying section for applying a pulsating voltage Vsp between the charging member and the object to be charged. The pulsating voltage Vsp is obtained by superimposing a voltage component of a direct current on a voltage component that periodically changes. The image forming apparatus is made to satisfy a relation of Vpp≦|Vth|, where Vpp is a peak-to-peak voltage value of the pulsating voltage Vsp and Vth is a charging start voltage value of the object to be charged. The relation prevents opposite charge from being imparted to residual toner on the object to be charged.

摘要： A network relay apparatus receives sub data different from main data by data transmission/reception processing units of a working system and a spare system, and when communication paths of the working system and the spare system are both working normally, makes the sub data flow through the communication path of the spare system. When a failure occurs in the communication path of the working system, the network relay apparatus switches the communication path for the main data to the spare system, and accordingly notifies it to a data relay unit, which is a relay destination of the main data. In the data relay unit, based on a notified content, corresponding relationships of ports in the unit are changed so that the received main data is output from the same output port as before.
