摘要： An image forming apparatus adapted for a smooth mounting/dismounting of a process unit and for the reduction of wasteful power consumption is provided. Unless a new image signal is applied after completion of an image forming operation, the apparatus starts a clocking operation by an internal timer (Step S101). If the apparatus is left standstill for a predetermined length of time (Step S102), a sleep process (Step S103) is executed to shift the apparatus to a power save mode to consume less power. When an outside cover is opened (Step S105), on the other hand, the apparatus is shifted to a replacement operation mode (Step S106) in which only the rotation of a development rotary is permitted. However, if the apparatus is left with the outside cover opened (Step S108), the sleep process is executed.

摘要： An image It is formed as a patch image which includes a header image portion Ih of a solid image having a length of a circumferential length of a developing roller or more, and a gradation image portion Ig progressively varied in the tone level thereof from the maximum level to the minimum level. The densities of the patch image on an intermediate transfer belt are sampled. However, the sampling results contain errors resulting from noises or variations and hence, are subjected to a noise removal process, a periodical variation correction process and a reverse correction process. The results detected on the intermediate transfer belt do not always coincide with image densities (OD values) on a recording material. Therefore, the detection results are converted into the OD values, based on which tone characteristics of an apparatus is estimated. Then a tone correction table is updated in a manner to compensate for the tone characteristics. This approach is taken to improve image quality on the recording material.

摘要： As a user turns on the power, patch processing (Step S104) is executed and image forming conditions are accordingly adjusted. However, when a setting entry for prohibiting the patch processing has been made at the time of power-on (Step S101, Step S103), after setting the image forming conditions to predetermined default conditions without performing the patch processing (Step S108), execution of an image forming operation is permitted (Step S107). The setting entry in this context is pressing of a particular switch by the user at the time of power-on.

摘要： When the remaining toner amount within a developer is relatively large, a control target value of a toner amount is set to Ttgt1 and a lower limit value of a toner amount which can regarded proper is set to TL1. When the density of a patch image formed under a predetermined condition is smaller than a minimum guaranteed density Dma, it is determined abnormality has occurred in the apparatus. Since the characteristic of toner within the developer changes as the remaining toner amount decreases, the control target value is changed to Ttgt2 and the lower limit value is set to TL2 in light of this. In this fashion, regardless of whether the toner characteristic has changed, abnormality in the apparatus is detected without fail.
摘要翻译： 当显影剂中的剩余调色剂量相对较大时，将调色剂量的控制目标值设置为Ttgt 1，将可以认为适当的调色剂量的下限值设置为TL 1。 当在预定条件下形成的贴片图像的浓度小于最小保证密度Dma时，确定在装置中发生异常。 由于显影剂中的调色剂的特性随着剩余调色剂量的减少而发生变化，所以根据此，将控制目标值改变为Ttgt2，将下限值设定为TL2。 以这种方式，无论调色剂特性是否改变，装置中的异常都被检测到。

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, 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.
摘要翻译： 来自密度传感器的输出信号Vp被采样到中间转印带上的多个位置，并且基于取样结果确定调色剂附着量。 由于这些样本数据可能含有噪声，因此从所得到的样本数据串中去除每个预定数量的高阶和低阶数据。 删除的数据片段被其他样本数据的平均值Vpavg替换。 调色剂附着量基于这样替换的数据串计算。
