摘要： Based on a video signal, a toner dot counter (802) and an off dot counter (801) detect a size of a toner dot portion to carry an adherent toner thereto and a size of an off dot portion not to carry an adherent toner, respectively. Reference is made to a look-up table (803) based on the detection results, so as to retrieve a coefficient (Kv) corresponding to a combination of the sizes of the toner dot portion and the off dot portion. A count value (Cdot) given by the toner dot counter (802) is multiplied by the coefficient (Kv), while the resultant product is integrated by an accumulator (805). An integration value for an image of one page is multiplied by a coefficient (K0) equivalent to a toner adhesion percentage of solid image. Thus is determined a toner consumption (TC) on the page image.
摘要翻译：基于视频信号，调色剂点计数器（802）和离点计数器（801）检测调色剂点部分的尺寸以携带粘附的调色剂和不携带粘附调色剂的断点部分的尺寸，分别。基于检测结果对查找表（803）进行参考，以便检索与调色剂点部分和断点部分的尺寸的组合相对应的系数（Kv）。由调色剂点计数器（802）给出的计数值（Cdot）乘以系数（Kv），而所得到的乘积由累加器（805）积分。将一页的图像的积分值乘以与实心图像的调色剂粘附百分比相当的系数（K0）。因此确定页面图像上的调色剂消耗（TC）。

摘要： Optimization of a density control factor accompanying formation of a patch image is executed every time a predetermined period of time elapses since the end of a preceding image forming operation. Since an image is formed at regular intervals in this manner, it is possible to suppress a density variation which is created as toner carried on a developer roller is left unused for long. This effect further improves when the developer roller is rotated idle prior to formation of a patch image or regularly at predetermined timing.
摘要翻译：每当从先前的图像形成操作结束起经过预定时间段时，执行伴随形成贴片图像的浓度控制因子的优化。由于以这种方式以规则的间隔形成图像，所以可以抑制由于在显影辊上携带的调色剂长时间不使用而产生的浓度变化。当显影辊在形成贴片图像之前或者在预定的时间定期旋转时，该效果进一步改善。

摘要： After forming solid patch images under various patch generating conditions (E, Vb), the optical densities of the respective patch images are measured by a patch sensor (PS), and patch generating conditions matching with a higher-density side target density (OD = 1.2) are extracted as "higher-density side correlation data." Further, line patch images are formed under various patch generating conditions (E, Vb), the optical densities of the respective line patch images (LI) are measured by the patch sensor (PS), and patch generating conditions matching with a lower-density side target density (OD = 0.2) are extracted as "lower-density side correlation data." An optimal exposure energy and an optimal developing bias are set based on one piece of correlation data (E2, Vb(3)) belonging to said product set of the higher-density side correlation data and the lower-density side correlation data.

摘要： Output signals Vp from a density sensor are sampled for plural positions on an intermediate transfer belt and an amount of toner adhesion is determined based on the results of sampling. Since these sample data pieces may contain noises (Vp(4);Vp(8);Vp(11);Vp(14);Vp(19)), each predetermined number of data pieces of higher order and of lower order are removed from the resultant sample data string. The removed data pieces are each replaced by an average value Vpavg of the other sample data pieces. The amount of toner adhesion is calculated based on the data string thus replaced.
