Original sheets in which both-side image information and one-side image information exist mixedly can be efficiently and certainly transmitted without an erroneous operation. A CPU discriminates the presence or absence of effective image information in images on both sides of the original sheets read by a reading circuit. In a both-side transmitting mode, the CPU selectively determines whether a both-side transmitting procedure is used or a one-side transmitting procedure is used, for transmission of the image information for each transmission of one original sheet, in accordance with a result of the discrimination. In the both-side transmitting procedure, control information such as page number, information regarding the front or reverse side of the original sheet, and the like is transmitted to a receiver station, for each side of the original sheet. In the one-side transmitting procedure, the control information is not transmitted or a proper transmitting system is used (the page number to be allocated to the front side assuming that the original sheet is the both-side original sheet is used, or the like). When the number of one-side original sheets is small, all of the original sheets may be transmitted by using the both-side transmitting procedure.
