PROBLEM TO BE SOLVED: To provide a facsimile machine provided with a means for informing the presence / absence of reception functions of various image information items with respect to color spaces, so as to effectively perform communication of color information. SOLUTION: A FIF of a DIS signal includes 68th to 75th bits for informing the presence/absence of reception functions of various image information items using a color space Lab and also includes an Xth bit for informing the presence/absence of reception functions of various image information items using a color space sYCC in the facsimile machine capable of communicating color image information. Further, a transmitter side facsimile machine uses the 69th to 75th bits of the FIF of the DIS signal for bits of informing the presence/absence of reception functions of various image information items using the color space sYCC and transmits again the resulting DIS signal in the case that '1' is set to the Xth bit of the FIF of the DIS signal so that a receiver side facsimile machine informs the transmitter side facsimile machine about the presence of the reception function of the image information using the color space sYCC, and in the case that '1' is also set to the Xth bit of the DCS signal from the transmitter side for the designation of the transmission in the color space sYCC.
