Title:
CONDUCTIVE ROLLER
Document Type and Number:
Japanese Patent JP2001082451
Kind Code:
A
Abstract:

To prevent an image failure and the like by forming a conductive elastic layer of polyurethane formed with polyol having carbon-carbon double bond in the molecule, as a polyol component, and forming the outer periphery as a toner non-sticky surface in a conductive roller with the conductive elastic layer concentrically formed at the outer periphery of a rotating shaft.

This conductive roller such as a developing roller, a transfer roller or a charged roller used for an electrophotographic device comprises a conductive elastic layer 13 concentrically formed at the outer periphery of a rotating shaft 12. The conductive elastic layer 13 is formed of polyol with carbon-carbon double bond in the molecule, and polyurethane with polyisocyanate reaction-cured, and the outer peripheral surface is subjected to special treatment such as heating or ultraviolet irradiation to form a surface treated surface 14 non-sticky and high in durability. The rotating shaft 12 is formed of aluminum, stainless steel, or the like, and polybutadiene polyol or polyisoprene polyol is used as polyol with carbon-carbon double bond in the molecule.
