a recording unit configured to record a plurality of types of recording materials on a medium; and
a control unit configured to control recording by the recording unit, wherein
when performing recording on the medium in accordance with recording data for recording a plurality of types of recording materials in a same region on the medium,
the control unit identifies a first recording material with a relatively high recording density in the same region, and a second recording material with a lower recording density in the same region than that of the first recording material, based on recording data,
the control unit performs recording such that a second region in which recording is performed with the second recording material corresponding to the same region is smaller than a first region in which recording is performed with the first recording material corresponding to the same region, and
when an attribute of an image represented by the recording data is a first attribute corresponding to a letter or a ruled line, the control unit increases a difference between the first region and the second region corresponding to the same region than when the attribute of the image represented by the recording data is a second attribute that is not the first attribute.
