A facsimile machine receives image data from a facsimile machine of another end. A Random Access Memory (RAM) stores a measured average value and fluctuation of an Eye Quality Monitor (EQM) value of the image data, and a number of error lines of the image data as an EQM data table. In past facsimile communication, a main control unit receives a training signal from the facsimile machine of the other end, and executes a training process. The main control unit measures an average value and fluctuation of an EQM value of the training signal, and compares the measured average value and the fluctuation of the EQM value with the average value and the fluctuation of the EQM value stored in the EQM data table. When there is no match, the main control unit executes the training process again.
