An image processing device of the present invention includes a region separating section and a filter processing section. With respect to a picture signal which is read out after resolution thereof in a sub scanning direction has been converted, the region separating section computes maximum density difference and complexity as feature parameters indicative of a characteristic of each pixel in the picture signal. Additionally, with respect to the complexity which is dependent on a size of the resolution in the sub scanning direction, the region separating section carries out a correction in accordance with the size of the resolution in the sub scanning direction, and separates the picture signal into each region by using the maximum density difference and the corrected complexity. In accordance with the size of the resolution in the sub scanning direction and each region separated by the region separating section, the filter processing section performs suitable image processing of the picture signal.

An image forming apparatus of the present invention includes main control section for controlling the charging control section and the development bias control section so that a potential difference between the photoconductor potential and the development bias potential in developer discharge from the development section is smaller than that in the image forming. Therefore, even when an amount of developer in the development section decreases due to developer discharge, increase of beads-carry-over onto the photoconductor from the development section can be prevented. Accordingly, damage to the photoconductor or image errors due to incomplete cleaning that are caused by beads-carry-over can be prevented.

The developing device according to the present invention includes a developing tank for containing two-component developer, a toner density sensor, and a toner cartridge. Further, the developing device according to the present invention includes a control section for inputting, to the toner density sensor, a control voltage (Vc) for correcting a sensor output. The control section sets the control voltage (Vc), by using a standard control voltage having been set so as to correspond to each of the stirring velocities, so that a sensor output (Vo) has a value within a range indicative of predetermined toner density. With the arrangement, it is possible to set the toner density sensor so that the toner density sensor operates in the most suitable manner so as to correspond to each of the stirring velocities, thereby realizing a developing device capable of detecting toner density with high accuracy.
