Image forming apparatus for storing sampling values and method therefor
An image forming apparatus includes an image forming unit configured to form a density detection pattern and a reference pattern on an image carrier by a developer; a light-receiving unit configured to receive reflection light of light emitted toward the image carrier, and output a signal corresponding to an amount of received light; a sampling unit configured to sample the signal output from the light-receiving unit, and store sampling values in the storage unit; a detection unit configured to detect the reference pattern; and a determination unit configured to determine a sampling value corresponding to reflection light from the density detection pattern of the color among the sampling values stored in the storage unit, based on a detection time of the reference pattern.
