To provide facsimile equipment that can strictly discriminate intermingled compressed/non-compressed data with a simple configuration.

The facsimile equipment converts read original image data into binary data and applies coding processing of intermingled compression/non- compression intermingled type to converted binary data. When a succeeding line is processed as a non-compression line, the coding processing is conducted by forcibly bringing a black level to a final bit of a line of raw data of its preceding line before compression and when the succeeding line is processed as a compression line, the coding processing is conducted by forcibly bringing a white level to the final bit of the line of raw data of its preceding line before compression.
