ABSTRACT:
An image forming apparatus comprises an image signal converting means. The image converting means converts a first image signal into a second image signal. The first image signal includes an n-bit digital signal indicating a tone level of an image. The second image signal includes an m-bit digital signal indicating the tone level of the image. Here, m and n are integers and m is greater than n. A predetermined relationship between 2.sup.n values expressible by the n-bit digital signal and 2.sup.n related values among 2.sup.m values expressible by the m-bit digital signal is according to a first image forming characteristic in the image forming apparatus. The image forming apparatus further comprises an image forming means having a second image forming characteristic. The image forming means is coupled to the image signal converting means and forms the image based on the second image signal related to a combination of the first and second image forming characteristics.
