    摘要： A charging member including an elastomeric member including an elastomeric material. The elastomeric material includes a polymer dispersion medium having a double oxide dispersed therein, the double oxide being a solid solution compound of oxides of at least two different metals formed by crystal lattice substitution. The at least two different metals have different valences, whereby the double oxide has an electroconductivity that is larger than that of either one of the oxides of at least two different metals when not in solution. Also, the charging member has resistance stability in the semiconductive region.

    摘要： A method of manufacturing optical elements which is capable of obtaining optical elements at high accuracy by molding through employment of an optical element molding glass material preliminarily processed to prevent such defects as crack formation or chipping at the corner portions of the molding material which contact dies when the material is charged into the mold. An optical element molding glass material to be employed for the above method is formed with curvatures at boundary portions i.e. corner portions where its cylindrical portion contacts at right angles with its end flat portions by applying chemical etching, heat of a carbon dioxide gas laser or radiation heat to such corner portions. Meanwhile, in the manufacturing process of the optical element in which upper and lower dies and the preliminarily processed molding material are subjected to molding through heating and pressurization in a contacted state at all times, the molding pressure is arranged to be reduced at least one or reduced to zero to provide the optical element at high accuracy.
