    摘要: A developer for electrostatic electrophotography which comprises a composition of colorant particles, an electric charge supplying agent and a resin binder dispersed in a dispersion medium. The resin binder is a copolymer which has a polyoxyethylene units at side chains thereof, so that the interaction with the electric charge supplying agent is improved. The resultant developer ensures good resolution, gradation and fixing property and is suitable for wet development to give high-quality images. When the copolymer used as the resin binder has styrene units therein, its solubility in the dispersion medium is improved. The developer is either liquid or solid depending on the type of dispersion medium.

    摘要: Disclosed herein are an ionic conductor including a proton conductor, a process for production thereof, and an electrochemical device (such as fuel cell) with said ionic conductor, said ionic conductor being superior in ionic conductivity, water resistance, and film forming properties. The ionic conductor is formed from a polymer in which carbon clusters having ion dissociating functional groups are bonded to each other through connecting groups. The polymer is less water-soluble and more chemically stable than a derivative composed solely of carbon clusters; therefore, it permits many ion dissociating functional group to be introduced thereinto. Moreover, if ion dissociating functional groups are introduced into also the connecting group, it is possible to prevent the concentration of ion dissociating functional groups from decreasing as the result of polymerization. The polymer can be easily synthesized by simple condensation, substitution, and hydrolysis. Therefore, the process is suitable for mass production in high yields.
