Abstract: PROBLEM TO BE SOLVED: To provide an intermediate transfer member capable of ensuring resistance in a desired range according to a printing step. SOLUTION: In a toner transfer system for a xerographic copier in which charged toner particles are transferred once to the intermediate transfer member and then transferred to a copying sheet or the like, the intermediate transfer member is composed of a polyimide substrate 40 in which a polyanaline electrically conductive filler and a carbon black electrically conductive filler have been dispersed and an outer layer 41. By this structure, controllable resistivity can be imparted to the intermediate transfer member and a desired electric field for transfer corresponding to the speed of a printing step can be provided in such a range as not to cause dielectric breakdown in the transfer of a toner.

Abstract: PROBLEM TO BE SOLVED: To solve the problem of reverse transfer of toner cleaned from a fuser cleaning web to a fuser roll, which induces a mark on a copy (MOC: Marks On Copy).
SOLUTION: The fuser system 1 includes the fuser roll 2, the cleaning web 3, a pressure roll 4, and a paper-toner feed mechanism 14. The chemical charge control agents or inducers 5 are applied or coated by cleaning web 3 on the fuser roll 2 to control the magnitude and polarity of the voltage on the fuser roll surface to form a surface coating 6 containing the chemical inducer(s) 5. This will repel the negative toner at the entrance to the fuser nip 13 and prevent the toner 17 from transferring to the fuser roll 2 at the entrance of the fuser nip 13 and preclude the formation of NVO and consequently prevent MOC.

Abstract: PROBLEM TO BE SOLVED: To provide a BCR system which has superior charge uniformity and less wear, and which is more inexpensive.
SOLUTION: A biased charge roller (BCR) 1 is constituted, by arranging many electrodes on an insulating substrate layer 10 and covering them with a semiconductor layer 9. The electrodes 8 are applied with bias voltages VP
