An image forming apparatus includes: an image forming unit configured to form an image pattern on a medium, a predetermined image repeatedly appearing in a first cycle in a sub scanning direction in the image pattern; a density detector configured to optically detect a density of the image pattern in the sub scanning direction; a cyclic image detector configured to detect a feature image having a second cycle corresponding to the first cycle in accordance with a result of the detection; and a state determining unit configured to determine whether a cycle depending on an outer circumference of a rotary member included in the image forming apparatus corresponds to the second cycle when the feature image is detected by the cyclic image detector, and determine that a state of the rotary member has deteriorated when the cycle depending on the outer circumference is determined to correspond to the second cycle.

A recording device includes 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. 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, and 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.
