In a remote support system, an image forming apparatus, a staff terminal, and a management apparatus are connected to one another for communication. The management apparatus accumulates a conversation pattern communicated in a conversation form between the image forming apparatus and the staff terminal, and when the management apparatus receives a guidance request from the image forming apparatus, the management apparatus forces the staff terminal to display a selection screen that displays, as choices, the conversation patterns, and forces a request sending apparatus to display a selected conversation pattern as a guidance.
