摘要： Based on a video signal, a toner dot counter and an off dot counter 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 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 is multiplied by the coefficient Kv, while the resultant product is integrated by an accumulator. 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： The number of toner dots to be formed or tone values of the respective dots are integrated and thus found count is multiplied by a predetermined coefficient, thereby calculating a toner consumption amount. As a value (E1 or E2) to which exposure power E is set to attain a target density Dlow is different from a theoretical optimal value (Eopt1 or Eopt2), an image density becomes slightly different from the target density, which causes an error in calculating the toner consumption amount. To suppress this, the coefficient substituted in a formula for calculating the toner consumption amount is changed depending upon a deviation (ΔE1 or ΔE2) between the set value and the optimal value.

摘要翻译： 要形成的调色剂点的数量或各个点的色调值被积分，因此发现计数乘以预定系数，由此计算调色剂消耗量。 作为将曝光功率E设定为达到目标密度Dlow的值（E 1或E 2）与理论最佳值（Eopt 1或Eopt 2）不同，图像浓度与目标密度略有不同， 在计算墨粉消耗量时引起错误。 为了抑制这一点，用于计算调色剂消耗量的公式中所取代的系数根据设定值和最佳值之间的偏差（ΔE1或ΔE2）而改变。
