CONDUCTIVE MEMBER AND ITS MANUFACTURE, AND IMAGE FORMING DEVICE USING IT

摘要

PROBLEM TO BE SOLVED: To obtain a conductive member in which the increase of electric resistance by continuous energizing is small, and between the varying width of the electric resistance at the time of a low temperature and a low humidity and that at the time of a high temperature and a high humidity is small, and which is suitably used as a developing member and an electrifying member for electrophotographic processing. SOLUTION: The electric resistance with measuring voltage of 1000V under the conditions of temperature 15 deg.C and relative humidity 10% is equal to or below ten times of the electric resistance with measuring voltage 1000V under the conditions of temperature 32.5 deg.C and relative humidity 85%, and also the electric resistance with measuring voltage 1000V under the conditions of temperature 15 deg.C and relative humidity 10% after continuously energizing by electric power 10mW is made equal to or below three times of the electric resistance with measuring voltage 1000V under the same conditions as before continuous energizing.
