It is so arranged that even if a procedure which does not report the number of lines of an image before image information is transmitted gives rise to an error, the occurrence of the same error can be prevented when a message is re-transmitted. To accomplish this, a reading circuit (14) reads a JPEG color image when facsimile transmission of the image is performed in a direct transmit mode. While the image is being stored in a memory (18), the number of lines in the image is counted. If the number of lines counted attains a predetermined number, the image is encoded in accordance with the JPEG standard and then is transmitted. Here the number of lines is transmitted as zero before the image information is transmitted. If an error occurs on the receiving side, the image is re-transmitted. At re-transmission, the counted number of lines is transmitted before the image information.
