摘要： An image forming apparatus includes at least one photoconductive medium on which an electrostatic latent image is formed; at least one developing device for developing the electrostatic latent image formed on the photoconductive medium with a developer to form a visible developer image, and a developing performance improving unit for controlling at least one of the photoconductive medium and the developing device to periodically form a patch developer image using developer that has uneven attributes (such as uneven coulomb per mass (Q/M)), and clean and remove the patch developer image. Accordingly, developer having uneven Q/M is periodically used for printing patch developer image and removed, thereby preventing the developer from being used for desired images, and thereby preventing inferior developing of desired images at the uneven-developer generating parts.

摘要： A charging voltage supply and a method for supplying a charging voltage are provided. The charging voltage supply generates a voltage and branches the generated voltage to at least one charging roller according to voltage applied to a transfer roller. Accordingly, the charging voltage supply can compensate for the charging voltage in view of the reduction of a charging potential of a photosensitive body according to the transfer voltage.

摘要： A tone compensation method for a color printer and a color printer having a tone compensator are provided, wherein the method includes the steps of (a) acquiring a reference tone reproduction curve of print colors based on a printing environment, (b) forming sample patterns for one or more colors on a predetermined object medium, (c) forming a sectional tone reproduction curve by using the sample patterns, and (d), adjusting one or more print variables to compensate the sectional tone reproduction curve in order to reduce sectional errors between the reference tone reproduction curve and the sectional tone reproduction curve. Accordingly, it is possible to provide a tone compensation method capable of compensating for a sectional tone reproduction curve to approximate a reference tone reproduction curve without complicated mathematical calculations, and which is substantially unaffected by external disturbances and noise.
