摘要： The content of processing of an input image signal varies depending upon the conditions of an apparatus. In view of the fact that this results in the variations of correlation between tone data and toner consumption, a coefficient by which an integration value of the tone data is defined according to the content of the signal processing. In an image forming apparatus which performs tone correction as the signal processing and which has a characteristic (2) of forming images of higher densities relative to tone levels, for example, a larger amount of toner is consumed. Therefore, the coefficient of the apparatus is defined to be a higher value than that of an apparatus having a substantially linear characteristic (1). Conversely, in the case of an apparatus having a characteristic (3) of forming images of lower densities, thus consuming less toner, the coefficient is defined to be a lower value.

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： An image forming apparatus and an image forming method, which are capable of forming images at stable image quality by executing adjustment of operating conditions at appropriate timings, are provided. When a Vsync count corresponding to an integrated value of a rotation count of an intermediate transfer belt reaches a predetermined value V1 or V2, a charging current Iw is increased by one level and an adjusting operation of a developing bias is executed (at a time t4 or t5), to thereby stabilize an image density. Further, when remaining service life of a developer reaches a predetermined value (50%) (at a time t6), if the Vsync count at that moment suggests that the time to change the charging current Iw is drawing near, the change thereof is executed ahead of the schedule, whereby the adjusting operation of the developing bias, which should otherwise be executed at the time t7, is omitted.
