摘要： Provided are an image forming apparatus and an image forming method capable of easily forming an output image having desired gradation characteristics and capable of reducing running cost. In an intermediate transfer-type image forming apparatus, an image forming section is configured by including a first image forming section which forms a color toner image on a photoconductor, and a second image forming section which is located on the upstream side of the first image forming section and forms a transparent toner image on the photoconductor. Further, after the transparent toner image is formed on an intermediate transfer member by the second image forming section, the first image forming section forms, on the basis of image data (correction gradation values) corrected by a gradation correcting section, a color toner image so that the color toner image is superimposed on the transparent toner image.

摘要： A printer control unit carries out a predetermined calculation based on the amount of adhering toner detected by an AIDC sensor and the surface potential of a photoconductor detected by a V sensor to correct the light emission intensity of a light source to prepare light emission characteristic data for .gamma. correction to obtain an optimal image. A .gamma. correcting unit corrects an image signal output from an image signal processing unit using the calculated light emission characteristic data for .gamma. correction to control the light source to emit light based on the corrected data. More specifically, since the .gamma. correction data is obtained by calculation, optimal .gamma. correction can always be carried out without a memory of a large capacity.
