Abstract: In an image forming apparatus connected to a network, an interface unit receives information requesting data via the network and transmits response data to the network during a normal mode and a standby mode. A storage unit stores the response data being read out during the standby mode. A normal-mode response data generating unit generates the response data during the normal mode. An information storing unit, during the normal mode, stores, in the storage unit, information about the response data. A standby-mode response data generating unit, during the standby mode, generates the response data from the information about the response data, and stores a response frequency of the information. A stored response data deleting unit deletes, if an amount of the information exceeds a storage capacity of the storage unit, the information with the response frequency that is lower than a specified threshold.

Abstract: Provided is a responding apparatus that performs a network response in the standby mode and is not required much time for transitioning to the standby mode. The responding apparatus receives information request data from a network and transmits response data corresponding to the information request data to network, in the normal mode and standby mode. A normal mode response data making part makes response data in the normal mode. A recursive response request part recursively transmits information request data that requires information of other response data to the normal mode response data making part in the normal mode. An information storing part accumulates the information of the other response data corresponding to the information request data. A standby mode response data making part makes response data from information accumulated by information storing part in the standby mode.

Abstract: A photoconductive device having a photoconductive layer which includes an amorphous semiconductor layer capable of charge multiplication in at least a part thereof is disclosed. The method of operating such a photoconductive device is also disclosed. By using the avalanche effect of the amorphous semiconductor layer, it is possible to realize a highly sensitive photoconductive device while maintaining low lag property.
