IMAGE FORMING APPARATUS, METHOD FOR CALIBRATING PRINT DENSITY, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

An image forming apparatus, a method, and a non-transitory computer-readable recording medium are provided. The apparatus includes an image former configured to form patches for print density calibration on an image forming medium, a print density sensor configured to sense a print density for the plurality of reflective patches formed on the image forming medium, a calculator configured to calculate calibration coefficients of the sensor based on the sensed print densities, and a calibrator configured to perform the print density calibration using the calculated calibration coefficients.
