Summary:To improve the accuracy in calculation of the usage of developer.SOLUTION: A printer (100) executes acquisition processing of acquiring gamma correction data based on the densities of exposure performed by exposure units (2) and the densities of developer images formed by developing units (3), conversion processing of converting multi-gradation print data into multi-gradation gradation data by applying the gamma correction data, and calculation processing of applying inverse gamma correction data to the gradation data to create multi-gradation density data and calculating the usage of developer from the density data.SELECTED DRAWING: Figure 1 【課題】現像剤の使用量の算出の精度を向上させる。【解決手段】印刷装置(100)は、露光部(2)による露光濃度と、現像部(3)により形成された現像剤像の濃度と、に基づいて、ガンマ補正データを取得する取得処理と、多階調の印刷データを、ガンマ補正データを適用して多階調の階調データに変換する変換処理と、階調データに逆ガンマ補正データを適用して多階調の濃度データを生成し、濃度データから現像剤の使用量を算出する算出処理と、を実行する。【選択図】図1
