摘要： A small domain generation section generates a plurality of small domains in a multi-valued image transmitted from an intermediate tone correction section. Each domain is constituted of a plurality of pixels. Counting means counts a signal input value of each pixel. Weighting calculation means corrects each signal input value of the “pixels subjection to toner quantity equivalent value calculation” with reference to the signal input value of the small domain, and reads out a weighting coefficient from the weighting coefficient table based on the modified signal input value. The weighting calculation means multiplies the signal input value by the coefficient so as to convert the signal input value into a toner quantity equivalent value. Accumulating means calculates toner quantity equivalent values for all of the pixels of the multi-valued image. A total toner quantity equivalent value calculation section determines a total toner quantity equivalent value by accumulating all of the toner quantity equivalent values which are individually calculated each time an image is processed. When the total toner quantity equivalent value reaches a predetermined value, conditions for process control is set. On this account, the present invention achieves an image forming apparatus capable of accurate estimation of toner consumption quantity.

摘要： In a case where the density correction condition of an image output section is satisfied while a job is being executed, density correction means performs density correction while the job is being executed or after the execution of the job. On this occasion, if there is a job on standby for printing in an image memory, this job is executed in the image formation condition (i.e. a correction amount stored in a current correction amount storing section) determined before the density correction. In the meanwhile, a job which is stored after the density correction is executed in a latest image formation condition (i.e. a correction amount stored in a latest correction amount storing section) which is figured out by the aforesaid density correction.

摘要： An image forming apparatus includes: toner supply amount detecting means for detecting a toner supply amount to a developer tank; detecting means for detecting a signal value of each pixel of an image; and toner consumption amount estimating means for estimating a toner consumption amount, based on the signal value. The signal value detected by the detecting means is corrected in accordance with the toner supply amount detected by the toner supply amount detecting means. The toner consumption amount is estimated based on the signal value corrected. This allows the toner consumption amount to be always calculated accurately, regardless of a variation amongst various models, or a variation in a toner consumption characteristic due to aging, using environment, or the like.

摘要： A contact charger includes a photoreceptor having a photosensitive layer formed on a surface of an electrically conductive drum base and a fixed coil connected to the drum base and ground. The contact charger charges the photosensitive layer by making a charge roller in contact with the photosensitive layer while being applied thereto DC voltage from a power supply. With this arrangement, in the case where a pin hole exists on the photosensitive layer, there may have a continuity between the charge roller and the drum base which may results in a sudden increase in current flowing between the drum base and ground. When this happens, however, since self-induced electromotive force, having a direction opposite to the electromotive force of the power supply, is generated by the fixed coil in response to a sudden increase in current, excessive current will not flow between the drum base and ground, thereby eliminating the possibility of a large drop in voltage of the power supply. As a result, the contact charger is always capable of appropriately charging the surface of the photosensitive layer even in the case where a defect such as a pin hole exists on the photosensitive layer.
摘要翻译：接触充电器包括具有形成在导电性鼓底座的表面上的感光层的感光体和连接到鼓底座和接地的固定线圈。接触充电器通过使充电辊与感光层接触，同时从电源施加到其上的DC电压来对感光层充电。利用这种布置，在感光层上存在针孔的情况下，充电辊和鼓座之间可能具有连续性，这可能导致在鼓底座和地面之间流动的电流突然增加。然而，当发生这种情况时，由于响应于电流的突然增加，具有与电源的电动势相反的方向的自感应电动势由固定线圈产生，所以过大的电流将不会在鼓基并接地，从而消除了电源电压大幅度下降的可能性。结果，即使在感光层上存在诸如针孔的缺陷的情况下，接触充电器总是能够适当地对感光层的表面充电。
