Title: Development machine and imaging device
Inventor: TSUKAMOTO TAKEO
IPC: G03G15/11
Filed: 2001-06-12
Abstract: PROBLEM TO BE SOLVED: To restrain the deterioration of developer and to make the operation of an entire image forming device stable, while keeping image quality by restraining the irregularity of image density, even if image forming speed is high. SOLUTION: By counting the number of pixels per unit time, based on image data and calculating the changing speed of image area (area-changing speed) from the number of pixels, toner consumption (toner consumption rate) per unit time is calculated. Revolving speed ω of a 1st carrying screw for carrying the dry two-component development in the shaft direction of a developing roller, while bringing the developer into contact with the developing roller is decided, based on the toner consuming speed, so that the difference in image density (unevenness of image density) corresponding to both ends in the shaft direction of the developing roller falls within the range of 0.1 to 0.2.  Since the revolving speed of the 1st carrying screw is made low when an image area rate is small, needless friction caused in the developer is reduced, and the heat generation and the deterioration of the developer is restrained minimum.
