Abstract:
1. An image forming apparatus comprising: a search request transmission unit configured to transmit a search request to a predetermined resource in a network; a response receiving unit configured to receive response information in response to the search request, and store the received response information in a storage unit; a list screen display control unit configured to cause a display unit to display a list screen including a display element corresponding to each response information stored in the storage unit within a first predetermined time period since the transmission of the search request, wherein when the list screen is changed to another screen and then changed back again to the list screen, the list screen display control unit causes the display unit to display the list screen in a manner such that the list screen includes the display element corresponding to each response information stored in the storage unit within the first predetermined time period and each response information stored in the storage unit after the first predetermined time period has passed, the search request transmission unit transmits the search requests by using a multicast method and by using a unicast method to address information stored in a non-volatile storage unit, the response receiving unit stores the response information in a volatile storage unit, the list screen display control unit causes the display unit to display the list screen based on the response information stored in the volatile storage unit, the image forming apparatus further comprises: the search request transmission unit transmits the search request by using the unicast method to address information having been moved to the volatile storage unit, the deletion unit deletes the address information having been moved to the volatile storage unit each time when being searched for; and when the response information in response to the search request by using the unicast method to the address information having been moved to the volatile storage unit is received within the second predetermined time period, the response receiving unit stores the address information in the non-volatile storage unit.
