摘要： A proximity charger roller is disposed in proximity to a surface of an image carrier and uniformly charges an effective charging area of the image carrier. Abutting portions abut on the image carrier at its both edges which are located on the outer side of the effective charging area, thereby maintaining the proximity distance between the circumferential surface of the proximity charger roller and the image carrier constant. A cleaning roller is longer than the spacing between the abutting portions which are at the both edges, abuts on the abutting portions which are at the both edges, and presses with predetermined pressing force in the direction of the image carrier. The surface of the cleaning roller is made of a soft material and cleans a surface area between the two abutting portions of the proximity charger roller.

摘要： A nip pressure at an inlet site of a nip portion 69 is higher than a nip pressure at an exit site of the nip portion 69. Thus, the relatively higher nip pressure is applied to a recording medium 4 at the inlet site of the nip portion 69 thereby squeezing out a carrier liquid L from space between toner particles T and between the recording medium 4 and the toner T. Hence, the amount of carrier liquid L remaining in the spaces is notably decreased. The recording medium 4 with a decreased amount of carrier liquid L carried thereon is moved to the exit site of the nip portion 69, where the toner T is brought into pressure contact with one side S1 of the recording medium 4 thereby to be fixed to the recording medium 4.
摘要翻译：压区部分69的入口部位处的压区压力高于夹持部分69的出口部位处的压区压力。因此，相对较高的压区压力被施加到压区部分69的入口位置处的记录介质4，从而从调色剂颗粒T之间和记录介质4与调色剂T之间的空间挤出载液L.因此，残留在空间中的载液L的量显着减少。携带有载体液体L的量减少的记录介质4被移动到辊隙部分69的出口位置，在该位置处调色剂T与记录介质4的一侧S 1压力接触，从而被固定到记录介质4。

摘要： Image data is inputted from a data processing means 123 into storage means 124 so that light emitting elements of one line 128a of a light-emitting element (yellow) line head 128 are activated to expose pixels on an image carrier according to an output signal form a shift resistor 124a. The image carrier is moved in the direction of arrow X in such a manner that the pixels reach a position corresponding to the light emitting elements in a next line 128b. At this point of time, the image data are transmitted to a shift resistor 124b and then outputted to the line 128b so as to expose the pixels again. The image data are transmitted among the shift resistors sequentially by moving the image carrier, thereby sequentially repeatedly expose the same pixels.
