摘要： In an apparatus which forms an adjustment toner image outside an image area in a direction orthogonal to a moving direction of an image bearing member, a toner change amount of the adjustment toner image which is directly transferred onto and adheres to a transfer roller without interposing a recording medium differs depending on a transfer electric field. Since the transfer electric field is in a direction for reversing a charging polarity of the toner, when the transfer electric field is large, the toner charge amount of the adjustment toner image is reduced. Therefore, in case that the transfer electric field is large, the cleaning electric field is set small. Thereby the toner of the adjustment toner image can be sufficiently cleaned off by an electrostatic cleaning member irrespective of the transfer voltage, and contamination on a back side of a recording material can be avoided.
摘要翻译：在与图像承载部件的移动方向正交的方向上形成图像区域外的调色剂图像的调色剂图像的调色剂变化量直接转印到转印辊上并附着在转印辊上，记录介质根据转印电场而不同。由于转印电场是反转调色剂的充电极性的方向，所以当转印电场大时，调色剂图像的调色剂充电量降低。因此，在转印电场大的情况下，将清洁电场设定得较小。由此，可以通过静电清洁部件充分地清除调色剂图像的调色剂，而与转印电压无关，并且可以避免记录材料背面的污染。

摘要： A reader unit A reads a pattern image formed on a first printing medium to obtain a first luminance value. A color processing unit converts into a density value using first conversion information. CPU creats an image processing condition LUTa based on the density value. A photo sensor reads a pattern image formed on an image carrier. CPU corrects LUTa based on a density value of the pattern image read by photo sensor. A printer unit forms a pattern image on a second printing medium different using the corrected LUTa. CPU determines second conversion information for the second printing medium based on a second luminance value from the pattern image on the second printing medium, the first luminance value and the first conversion information.

摘要： An image forming apparatus capable of keeping reproducibility and gradation in balance and outputting high-quality images. A primary electrostatic charger charges a photosensitive drum. A polygon scanner irradiates the drum with a laser beam to form an electrostatic latent image on the drum. A developing device develops the latent image into a toner image by applying a developing bias to the drum. In performing development by the developing device at a preset environmental contrast potential, a CPU determines a required contrast potential for obtaining a target maximum density. The CPU compares between the environmental contrast potential and the required contrast potential. Further, the CPU sets an upper limit value for a set contrast potential to be set to the developing device according to the result of the comparison, and sets an output level of the laser light to be output from the developing device.

摘要： An image forming apparatus is provided which is capable of preventing a drop in productivity even if a consumable such as toner is not replenished as expected. The image forming apparatus has a feature of shifting to a mode of saving the consumable if an arrival time of the consumable is determined to be later than a time when the consumable needs to be replenished, on the basis of the shipping status information on the consumable obtained from a management server and the calculated time when the consumable needs to be replenished.
