A data compression apparatus and a data compressing program storage medium attain a high compression rate and a high-speed compression speed in a binary image data compressing process. A data compression apparatus which performs a data compressing process on data to be compressed and formed by a sequence of values each expressed by a 1-bit value includes: a data conversion section which generates new data to be compressed, formed by a sequence of values each expressed by a 1-bit value that indicates whether or not an adjacent value is an equal value in the sequence of values; and a data compression section which performs a compressing process on the new data generated by the data conversion section.
