Abstract
A surface-modified blade rubber includes a surface modified by being subjected to irradiation treatment that generates radical active sites in the blade rubber and polymerization for graft polymerization starting from a generated radical active site. A method for modifying a blade rubber surface includes subjecting rubber of a blade rubber to irradiation treatment that generates radical active sites and polymerization for graft polymerization starting from a generated radical active site.
