Cleaning blade for use in image-forming apparatus
First Claim
1. A cleaning blade, for cleaning toner on a surface of a photoreceptor of an image-forming apparatus, which is formed by molding into a thin plate a thermosetting elastomer composition containing:
- a rubber component (1) consisting of a moderate high-nitrile acrylonitrile-butadiene rubber having a bound acrylonitrile amount of 31% to 36%, a hydrogenated acrylonitrile-butadiene rubber having a residual double bond content of not more than 10%, or a mixture of said rubbers, 0.1 parts by mass to 80 parts by mass of a filler (2) per 100 parts by mass of said rubber component (1), and 0.1 parts by mass to 30 parts by mass of a crosslinking agent (3) per 100 parts by mass of said rubber component (1),wherein said filler is either a combination of methacrylic acid, carbon black and magnesium oxide or a combination of zinc oxide, carbon black and stearic acid;
wherein an initial contact angle of said cleaning blade to said photoreceptor is set to 10°
to 50°
; and
wherein a line pressure of said cleaning blade to be applied to said photoreceptor is set to 0.1 N/cm to 1.5 N/cm.

Abstract
A cleaning blade, for use in an image-forming apparatus, which is formed by molding a thermosetting elastomer composition containing a rubber component consisting of acrylonitrile-butadiene rubber, natural rubber, butadiene rubber, styrene-butadiene rubber, isoprene rubber, butyl rubber, chloroprene rubber, acrylic rubber, epichlorohydrin rubber, ethylene propylene rubber, and ethylene-propylene-diene copolymer rubber or a mixture of two or more of the rubbers into a thin plate. An initial contact angle of the cleaning blade to the photoreceptor is set to 10° to 50°. A line pressure of the cleaning blade to be applied to the photoreceptor is set to 0.1 N/cm to 1.5 N/cm.
