摘要： The present invention relates to image forming device such as copying machines and laser printers, which use an electrophotographic (xerognaphic) process. A simple control method without using any additional complex means can equalize a surface potentional of a light-sensitive drum to keep a light-quality of an image formed even for the first rotation of the light-sensitive drum. A charge-removal prohibiting means, a charge-potentional changing means and a developing bias-potentional changing means are controlled in accordance with an extent of a change of a surface potential of a light-sensitive body, which depends upon a light fatigue and an ambient temperature of the light-sensitive body and/or a pause after a preceding image process.

摘要： 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.

摘要： The read out image data is stored in the mask memory in a predetermined mask unit, and binarized into binary value with a predetermined threshold in the binarizing circuit. The binarized image data is output to the main scanning direction-black pixel counting circuit and the sub scanning direction-black pixel counting circuit, respectively, to count black pixels in the main scanning direction and in the sub scanning direction, respectively. The largest value is determined by the comparator, and designated as the linkage degree. With the judging circuit, the area judgement of the character area, the photograph area and the dot area is performed based on the linkage degree.

摘要： A small domain generation section generates a plurality of small domains in a multi-valued image transmitted from an intermediate tone correction section. Each domain is constituted of a plurality of pixels. Counting means counts a signal input value of each pixel. Weighting calculation means corrects each signal input value of the “pixels subjection to toner quantity equivalent value calculation” with reference to the signal input value of the small domain, and reads out a weighting coefficient from the weighting coefficient table based on the modified signal input value. The weighting calculation means multiplies the signal input value by the coefficient so as to convert the signal input value into a toner quantity equivalent value. Accumulating means calculates toner quantity equivalent values for all of the pixels of the multi-valued image. A total toner quantity equivalent value calculation section determines a total toner quantity equivalent value by accumulating all of the toner quantity equivalent values which are individually calculated each time an image is processed. When the total toner quantity equivalent value reaches a predetermined value, conditions for process control is set. On this account, the present invention achieves an image forming apparatus capable of accurate estimation of toner consumption quantity.
