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.
摘要翻译：通过在不消耗调色剂的情况下校正调色剂浓度控制目标值，可以获得预定图像浓度的图像形成装置。比较磁导率传感器的输出值Vt和目标输出值Vtref，并根据其比较结果控制粉末泵来控制调色剂浓度，使得输出值Vt近似于目标输出值Vtref。此外，基于图像覆盖率的检测结果来校正目标输出值Vtref，以保持显影装置的预定显影电位。由此，即使在进行显影装置中的调色剂更换量的显着变化的图像形成的情况下，即使输出高图像覆盖率的图像，也可以调整调色剂浓度以保持显影能力恒定，并且确保了预定的图像浓度。此外，由于可以在不消耗调色剂的情况下检测图像覆盖率，当校正目标输出值Vtref时，不需要消耗调色剂。

摘要： In an embodiment, a diffuse reflection output conversion method is executed in an apparatus detecting a plurality of gradation patterns. The apparatus includes a light emitter and light receiver, and detects specular reflection and diffuse reflection simultaneously. A region before specular reflection saturation is a region where the specular reflection component decreases and saturates at minimum level. A diffuse reflection detector is calibrated by: obtaining a diffuse reflection output resulting from an amount of attached powder at a border between the region before specular reflection saturation and the region after specular reflection saturation; calculating a ratio between the diffuse reflection output and a reference diffuse reflection output calculated in advance as a calibration coefficient; and multiplying a diffuse reflection output obtained from the gradation patterns by the calibration coefficient calculated at the calculating.
