摘要： A toner density is calculated from outputs of light-receiving elements based on a difference between a reflection property of a supporting member and a reflection property of a toner pattern. Light-emitting elements aligned in one direction that is inclined to a sub-direction emit a detection light in such a manner that a distance between adjacent spots falling on the supporting member in a second direction is equal to or smaller than a width of the toner pattern in the second direction. The light-receiving elements receive a reflected light reflected from the supporting member and/or the toner pattern. The light-receiving elements are aligned, opposed to the supporting member, in a one direction corresponding to the light-emitting elements.

摘要： Upon setting of a halftone process of an initial setting, there is such a problem that graininess deteriorates due to an aging change or an environmental change. To solve this problem, an image processing apparatus executes a halftone process on a test image for tone correction and prints the processed test image; forms a tone correction table in accordance with read values from the printed test image; obtains graininess from a read value of a low density portion of a tone correction patch of the test image for the tone correction; discriminates whether the obtained graininess exceeds a predetermined reference level; and changes a setting of the halftone process so as to reduce the graininess when it is discriminated that the obtained graininess exceeds the predetermined reference level.

摘要： A toner image height measurement apparatus capable of accurately measuring heights of toner images of respective colors with a relatively simple construction and without being affected by toner colors. With motion of an image carrier, there occurs a change in reflection light amount detected by a photodiode of the height measurement apparatus in timing when laser light having been irradiated onto the image carrier starts to be irradiated onto or intercepted by a toner image and in timing when the laser light having been irradiated onto the toner image starts to be irradiated onto the image carrier. Based on a principle that these timings vary according to a toner image height, the height measurement apparatus detects the timing when the reflection light amount changes by a predetermined amount, thereby detecting the toner image height.

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。
