摘要： PURPOSE:To obtain a desired process response curve without being governed by a characteristic of a sensitized material, by controlling independently a developing efficiency of each magnetic roll and an applied developing bias. CONSTITUTION:When the potential of a developing bias 4 of a magnetic roll 1 is set to VB2, and a rotating speed is set to a suitable value, a development is executed to a density shown by a curve (b) on a drum 3. Thereafter, the drum 3 is moved to a position of a magnetic roll 2 and developed again. As for the potential on the drum 3 right before on the roll 2, the potential lowers a little as to a part developed by the roll 1. When the developing bias potential of the roll 2 is set to VB1 and a rotating speed of the roll 2 is set so that a density on the drum 3 developed by the roll 2 becomes as shown by a curve (a), a process response shown by a curve (c) which has placed the curve (b) on the curve (a) is obtained.

摘要： PURPOSE:To reduce moire and edge effect without decreasing resolution, by using a liquid crystal which has uniform light scattering characteristic to a low- frequency filter. CONSTITUTION:Once a scan is started, a mesh-point pitch sensor 52 generates an output signal corresponding to the state of mesh points on a platen. A CPU43 finds an applied voltage value from the contents of an ROM44 according to the generated signal and applies an optimum voltage from an output circuit 22 to a liquid-crystal cell 3 through an output interface 46. The cell has, for example, four-stages of opaqueness by the voltage application to provide four-stage filter characteristics. The transmittivity changes according to the change in the four- stage filter state, so a microcomputer 40 calculates the amount of exposure compensation to find a deficiency in the quantity of light, and controls an output circuit 21 to increase the quantity of light of a light source 1 to keep the quantity of light to a photosensitive drum constant. A picture of the photosensitive drum finished the exposure enters the next process.

摘要： PURPOSE:To eliminate a rough feeling on the highlight parts of an image and to obtain a color image rich in smoothness and naturalness by increasing the contents of a pigment in toner grains larger in grain diameter than those in the smaller toner grains. CONSTITUTION:The toner is composed of the grains larger in diameter and the smaller ones, and the larger ones are higher in the pigment contents than the smaller ones. The potential level of a photosensitive body corresponding to an image forming elements in a low-level region is made lower than the potential level in a high-level region by increasing laser beam intensity, thus permitting the smaller toner grains to develop the low-level region, and the larger toner grains to develop the high-level region, and accordingly, the image forming elements in the low-level region to be made lower in the density of the obtained image than those in the high-level region by transferring the toner image to a transfer paper and fixing it.

摘要： PURPOSE:To improve the granularity and color reproducibility of a polychromatic picture by providing the 2nd electrostatic charge process before a developing process after image exposure, and varying a leveling potential of each color between the white ground potential of an original and the potential of picture density to be reproduced. CONSTITUTION:The 2nd electrifier 3 is arranged between an image exposure station 2 and developing machines 4a-4c for three kinds of toner. When a DC constant voltage corotron is used as the 2nd electrifier 3, the leveling voltage VL is set between the potential VBG of the white ground part and the voltage Vn to be reproduced. Consequently, the potential of the white ground part rises up to V1 and the potential Vn of the density part rises up to Vn'. Namely, the unevenness of a surface potential pattern is leveled from a state shown by a broken line to a state shown by a solid line to reduce the intensity of a fringe electric field and also reduce the influence of edge effect, improving the granularity. Toner T is developed uniformly in proportion to the picture density to improve the color reproducibility.
摘要翻译：目的：通过在图像曝光之后的显影过程之前提供第二静电充电过程并改变原始白色接地电位和图像密度电位之间的每种颜色的调平电位，来提高多色图像的粒度和颜色再现性被复制。构成：对于三种调色剂，第二电气3设置在图像曝光站2和显影机4a-4c之间。当使用DC恒压corotron作为第二电气3时，将调平电压VL设置在白色接地部分的电位VBG和要再现的电压Vn之间。因此，白色接地部的电位上升到V1，密度部的电位Vn上升到Vn'。也就是说，表面电位图案的不均匀度从虚线所示的状态变为实线所示的状态，以降低边缘电场的强度，并且还减小边缘效应的影响，提高粒度。调色剂T与图像密度成比例地均匀地发展，以提高色彩再现性。
