Abstract
A photoconductor for electrophotography comprises an electrically conductive substrate and a laminate formed on the substrate. The laminate includes a charge generating layer including a specific squarylium compound as a charge generating substance and a charge transporting layer including a hydrazone compound. One type of the specific squarylium compound is represented by the following general formula. ##STR1## Wherein, each of R1, R2, R5 and R6 stands for one of an alkyl group, an aralkyl group and alkenyl group, each of which groups may be or not may be substituted, or R1, forms a ring together with R2, R5 forms a ring together with R6, each of R3 and R4 stands for one of hydrogen atom, a halogen atom, a hydroxy group, an alkyl group and an alkoxy group.
