    摘要： A supply control unit is configured to, in a successive image-forming operation, perform a process of successively generating a driving control pattern for a toner supply device based on image information of each page, and synthesizing an unused portion of the driving control pattern which is obtained by eliminating a portion of the driving control pattern already reflected on a driving control of the toner supply device from the driving control pattern generated based on image information of a previous page with a driving control pattern generated based on a subsequent page.

    摘要： An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The output value Vt of the magnetic permeability sensor and the target output value Vtref are compared, and the toner density is controlled by controlling a powder pump on the basis of the comparative result thereof so that the output value Vt approximates the target output value Vtref. In addition, the target output value Vtref is corrected on the basis of the detected result of the image coverage ratio so as to maintain a predetermined development potential of the development apparatus. By virtue of this, even when image forming that involves a significant change in the toner replacement amount in the development apparatus is performed, for example, even when an image of high image coverage ratio is output, the toner density is adjusted to maintain the development capability at a constant, and a predetermined image density is ensured. Moreover, because the image coverage ratio can be detected without consuming toner, toner does not need to be consumed when the target output value Vtref is corrected.

    摘要： An image forming apparatus in which a predetermined image density can be obtained by correcting a toner density control target value without consuming toner. The toner density of the developer is controlled so that an output value Vt of a magnetic permeability sensor approaches a target output value Vtref. In addition, the target output value Vtref is corrected in accordance with image coverage history information of output images transferred to a transfer paper and image coverage ratio history information of output images determined from the image coverage thereof and the size of the transfer paper. This history information comprises, for example, a cumulative average value of the image coverage or the image coverage ratio per transfer paper. It may also comprise a moving average value of the image coverage or the image coverage ratio per transfer material.
