Title:
CLEANING BLADE
Document Type and Number:
WIPO Patent Application WO/2016/208600
Kind Code:
A1
Abstract:
Provided is a cleaning blade 1 that has an elastic body 11, which is a molded body of a rubber substrate, and has at least a surface treatment layer 12 at a position that comes into contact with a contact-receiving body of the elastic body 11. The surface treatment layer 12 is formed by impregnating a surface part of the elastic body 11 with a surface treatment liquid containing an isocyanate compound and an organic solvent, and by curing same. The indentation elastic modulus of the surface treatment layer 12 is 21 MPa to 56 MPa. The indentation elastic modulus of the elastic body 11 is greater than 20 MPa but does not exceed 35 MPa. The difference between the indentation elastic modulus of the surface treatment layer 12 and the indentation elastic modulus of the elastic body 11 is 1 MPa to 21 MPa.
