摘要： It is an object of this invention to provide an image processing apparatus which, when nonmagnetic mono-component development is performed, prevents the formation of white gaps in pattern boundaries between different colors and thereby prevents degradation in the image quality of the formed image. To achieve this object, in one embodiment of the invention, the density value VD(n) of the nth pixel on a certain line is applied to the A input terminal of a selector 207, and the density value VD(n-1) of the (n-1)th pixel is applied to the B input terminal of the selector 207. A subtracter 203 calculates the increase of VD(n) from VD(n-1). If a comparator 204 determines that the increase is a predetermined value C1 or less, a selection signal in the selector 207 is so set that the terminal B (the value of the immediately preceding pixel) is selected.

摘要： By altering a developing bias, a plurality of patch images are formed on a photoconductor, and a density of each patch image is measured, thereby judging whether or not a target density value is within a range of the plurality of measured density values. If the target density value is outside the range, a developing bias which realizes the target density is obtained by an interpolation, in accordance with two measured density values that are closest to the target density value among a plurality of measured densities, and with a developing bias of two patch images that are related to these two measured density values.
