1. An image forming apparatus comprising:
a reading unit which reads image information on an original;
a first compression unit which compresses the image information read by the reading unit into compressed image information;
a first encoding unit which encodes the compressed image information;
an interface unit which acquires printing information in a page description language from exterior;
a generating unit which generates printing image information on the basis of the printing information;
a second compression unit which compresses the printing image information into compressed printing image information;
a second encoding unit which encodes the compressed printing image information;
a decoding unit which decodes the encoded compressed image information and the encoded compressed printing image information,
and which outputs the compressed image information and the compressed printing image information;
an expansion unit which expands the compressed image information and the compressed printing image information decoded by
the decoding unit; and
a forming unit which forms an image onto a recording medium on the basis of the image information and the printing image information
expanded by the expansion unit.
