Title:
CONDUCTIVE MEMBER AND ELECTROPHOTOGRAPHIC DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP3052749
Kind Code:
B2
Abstract:
PURPOSE: To provide a developing member which can not only obtain a high-quality image with low friction but also does not dispersion in performance in the production and a developing device using the developing member, and a conductive member applied to electrifying, transferring and cleaning devices and an electrophotographic device or an electrostatic recorder using the conductive member.
CONSTITUTION: As for the developing member for visualizing an electrostatic latent image by bringing an elastic layer carrying non-magnetic one-component developer into contact with an electrostatic latent image holding body, the conductive member functioning as the developing member is obtained by forming a 1st coating layer consisting of an elastic body 3 whose volume resistivity ρ1 is ≤107Ωcm on a conductive supporting body 2 and further a 2nd coating layer whose volume resistivity ρ2 satisfies ρ2/ρ1≥1000 and which is principally composed of any of soluble nylon, urethane- modified acrylic resin, modified polycarbonate and fluororesin, which does not contain conductive powder, on the 1st coating layer. Then, the conductive member as the developing member whose hardness is low, which is excellent in close adhesion property, which does not contaminate a photoreceptor, which has low friction, and where the dispersion in performance is not caused in the production, is obtained.
