Japanese Patent JP4662249
Kind Code:
B2
Abstract:
A development roller is provided which can ensure a desired surface roughness and roller hardness even when an elastic layer has not sufficient solvent resistance and which can be preferably used for a long period of time without generating any peeling of a coating film during a continuous long operation. In the development roller, an underlying conductive layer having at least one sublayer and a surface resin layer are provided on the elastic layer in that order. The elastic layer is formed of a foam material having a closed cell structure, the underlying conductive layer is formed from a water-based paint containing a conductive agent, and one of the sublayers of the underlying conductive layer that is in contact with the elastic layer is at least primarily composed of a chloroprene-methacrylic acid copolymer.
