Abstract:
An image forming apparatus comprising:generation means for generating an input image signal;setting means for setting output density of an output image signal to be formed in accordance with the input image signal;storage means for storing first density curve data representing a first relation between density of the input image signal and first density of the output image signal and second density curve data representing a second relation between the density of the input image signal and second density of the output image signal, the second density being higher than the first density;creation means for creating third density curve data representing a third relation between the density of the input image signal and a third density of the output image signal, based on the first density curve data and the second density curve data in accordance with the output density set by said setting means;conversion means for converting the input image signal generated by said generating means into the output image signal having a density determined by said third density curve data; andimage forming means for forming an output image on an image recording medium based on the output image signal converted by said conversion means,wherein said storage means further stores a fourth density curve data representing an output image signal having a density lower than the density of the first image signal.
