Abstract: The present invention provides an image forming apparatus that suffers less toner particles scattering and a narrower variation in image density. In this image forming apparatus, a decrease of a contrast potential difference can be compensated by means of a developing bias voltage generator circuit and a grid bias voltage generator circuit, so that the image density can be kept constant. The apparatus includes a developing mechanism in which the respective average particle diameters of carrier members and toner particles, toner concentration, and the diameter and peripheral speed of a developing roller are optimized. Although the diameter of the developing roller is small, therefore, a high image density can be secured, and the value of toner particles scattering can be lowered.

Abstract: A character recognition apparatus comprises a photoelectric conversion section that converts image information including the characters to be recognized into multi-valued image information according to image density, an edge extracting circuit that creates edge image information indicating the outline of image density on the basis of the multi-valued image information from the photoelectric conversion section, and a recognition circuit that computes a distribution of a direction component so as to create a feature vector and recognizes characters on the basis of the direction feature vector.

Abstract: A binarization circuit compares the density value of the target pixel with the density value of surrounding pixels in the vicinity. A judging unit judges whether or not the target pixel is isolated from the surrounding pixels. A detection unit detects the density values of the target pixels which make the target pixels isolated by a binarization process. A calculation unit calculates the accumulated isolated pixel frequencies of each density value detected by the detecting function when the judging unit and the detecting unit have finished processing all of the original image. A determination unit determines a threshold value on the basis of the accumulated isolated pixels frequencies.
