摘要： A photoconductor for electrophotography includes a conductive substrate and an organic undercoating layer on the conductive substrate. An organic charge generation layer is deposited on the undercoating layer, and an organic charge transport layer is deposited on the charge generation layer. The undercoating layer contains soluble polyamide resin and/or normal-butylated melamine resin as its main components. Alternately, the undercoating layer may contain resin as its main component, into which are dispersed small particles of anatase-type titanium dioxide. The surfaces of the anatase-type titanium dioxide particles may be treated with aminosilane. These undercoating layers produce a laminate-type photoconductor, which exhibits excellent electrophotographic characteristics that are stable during repeated use over long periods of time, and which vary little in a high temperature and high humidity atmosphere, as well as in a low temperature and low humidity atmosphere.
