摘要： The pressure between a developing roller and a photosensitive drum is set to 0.24 MPa. Because the pressure is smaller than 0.31 MPa, if the potential difference ΔV between the non-image forming part on the photosensitive drum and the electrically-charged polymer toner on the surface of the developing roller is at the preset proper voltage (300 volts), pressure fogging will be prevented. Because the pressure is 0.24 MPa or less, even if the potential difference varies within the range of 200 volts to 400 volts that occurs in practice, pressure fogging will be prevented. By resetting the pressure to 0.22 MPa, even if the potential difference ΔV varies in a wider voltage range of 100 to 400 volts, pressure fogging will be prevented. In this way, by setting the pressure between the developing roller and the photosensitive drum appropriately, pressure fogging can be prevented even when using the opposite-direction developing method and polymer toner.
摘要翻译：显影辊和感光鼓之间的压力设定为0.24MPa。由于压力小于0.31MPa，如果感光鼓上的非图像形成部分和显影辊表面上带电的聚合物调色剂之间的电位差DeltaV处于预设的适当电压（300伏），防止压力起雾。由于压力为0.24MPa以下，所以即使电位差在实际发生的200〜400V的范围内变化，也可防止压力起雾。通过将压力重置为0.22MPa，即使电位差DeltaV在较宽的100〜400V的电压范围内变化，也可防止压力起雾。以这种方式，通过适当地设置显影辊和感光鼓之间的压力，即使使用相反方向的显影方法和聚合物调色剂也可以防止压力起雾。

摘要： An apparatus for forming a multi-color is disclosed which includes a controller that performs an anti reverse-transfer control such that a surface potential of a previously-formed separated-developer-image subset of a plurality of single-color separated-developer-images which has been previously transferred onto an image transferred medium is reduced, prior to a subsequent transfer in which a remainder of the plurality of separated-developer-images is transferred onto the image transferred medium after a previous transfer of the previously-formed separated developer-image subset onto the image transferred medium, to thereby prevent a reverse transfer of a part of a developer material on the image transferred medium from the image transferred medium onto a photoconductor at the subsequent transfer.

摘要： A control section sets the transfer bias level applied between a transfer roller and a photosensitive drum in the printer to a “ghost generation level.” The control section forms a test pattern on the recording medium by applying a transfer bias set to the ghost generation level in order to transfer a toner image onto the recording medium. A density sensor detects the density of the toner image deposited in a non-image-forming region when the test pattern is formed. The control section estimates a transfer bias level, at which ghosts will not occur, based on the ghost generation level and the density level of the toner image in the non-image-forming region, and sets this estimated value as the transfer bias level for forming images.
摘要翻译：控制部分将打印机中的转印辊和感光鼓之间施加的转印偏压水平设置为“重影代数”。控制部分通过施加设置为重影产生电平的转印偏压来在记录介质上形成测试图案，以将调色剂图像转印到记录介质上。当形成测试图案时，密度传感器检测沉积在非图像形成区域中的调色剂图像的浓度。基于非图像形成区域中的调色剂图像的重影产生水平和浓度水平，控制部分估计不发生重影的转印偏压电平，并将该估计值设定为转印偏置电平形成图像。

摘要： A pressure sensor 16 has a length C and a width D identical respectively to a length A and a width B of a fluid pumping section 11 and is provided in a portion of a cover 15 opposite to the fluid pumping section 11. The fluid pumping section 11 has a structure for pressing a tube placed in a groove 13 by means of fingers which advance and retract in a cavity 14 formed in a wall 12 of a main body. A possible erroneous placement of the tube is detected according to a change of pressure force exerted from each of the fingers, detected by the pressure sensor 16 . The pressure sensor 16, which is provided within a range in which the fingers can press the tube, can detect even a slight displacement, of the tube from the range in which the fingers can press the tube, to thereby allow detection of erroneous tube placement free of a dead zone to be achieved.

摘要： A vehicle seat is disclosed which is provided on its surface with a plurality of intersecting, recessed grooves for decoration. The seat includes a cushion member formed of a foam material and provided on its surface with a plurality of intersecting, recessed grooves. Projections are provided adjacent to the intersections of these recessed grooves, respectively. Such projections can prevent wrinkles from being produced in the intersections of the decorative recessed grooves formed in a top member which is a component of the seat. Specifically, when such top member placed over the cushion member is hung in along the recessed grooves of the cushion member, the recessed grooves for decoration are formed on the surface of the top member. During this hang-in operation, the projections are compressed so that repelling resilient forces are produced in these projections. Such resilient forces of the projections prevent any wrinkles from occurring in the intersections of the decorative recessed grooves in the top member.
摘要翻译：公开了一种在其表面上设置有用于装饰的多个相交的凹槽的车座。该座椅包括由泡沫材料形成并在其表面上设置有多个相交的凹槽的缓冲件。分别在这些凹槽的相交处附近设置突出部。这样的突起可以防止在形成在作为座椅的部件的顶部构件中的装饰性凹槽的交叉处产生褶皱。具体地说，当放置在缓冲构件上方的顶部构件沿着缓冲构件的凹槽悬挂时，在顶部构件的表面上形成用于装饰的凹槽。在该悬挂操作期间，突起被压缩，使得在这些突起中产生排斥弹性力。突起的这种弹性力防止在顶部构件中的装饰性凹槽的交叉点中发生任何褶皱。
