Abstract
The invention provides a method for manufacturing a polysiloxane resin with charge transporting property by uniformly dissolving a charge transporting material to a practical concentration in a polysiloxane resin. The charge transporting material that is dissolved in the polysiloxane resin is an aromatically substituted tertiary amine which has been modified by substitution of one or more of the aromatic groups with a hydrocarbon group containing a silyl group with hydrolyzable substituents.
