Semiconductive members such as charging members, copying members, pressure fixation rolls, electricity removing members and the like having a small environmental dependence are provided. The semiconductive member of the present invention contains a semiconductive substrate, a conductive rubber layer, an intermediate layer, a resistance control layer the constituent material of which is a polyurethane ionomer having an ionic segment in the molecule, and a surface layer. The ionic segment is selected from among a sulfonic acid group, a carboxyl group and a tertiary amino radical, or the salts thereof. In addition, the glass transition temperature of this polyurethane ionomer is 30.degree. C. or less, and the volume specific resistance value is in the range of 10.sup.6 to 10.sup.9 W cm.

Semiconductive member and production method thereof

A device for photoelectric conversion and a process for fabricating the device are provided. The device exhibits superior dark current characteristics, and therefore a superior contrast ratio. The device is arranged to reduce or eliminate the vertical component of an electric field under an area where an ohmic contact, rather than a Schottky barrier, exists. The device can be fabricated using process equipment that sputters one or more of the device layers, including the wiring metal.
