Photoconductor for electrophotography

A photoconductor for electrophotography, comprising:

• an electroconductive substrate;
• and
• a photosensitive layer which is a monolayer formed on the electroconductive substrate and which contains a charge generating substance, a charge transporting substance, and a binder resin, the charge generating substance and the charge transporting substance being dispersed in the binder resin;
• wherein the charge transporting substance consists of a diamine compound represented by general a general formula (I) ##STR179## where R.sub.1 and R.sub.2, which are the same or different, each represent independently an alkyl group, an alkoxy group, or a halogen atom;
• where R.sub.3 and R.sub.4, or R.sub.5 and R.sub.6, combine together with a nitrogen atom to which they are bonded and form a 5- to 14-membered monocyclic heterocyclic ring having a nitrogen atom as a hetero atom and being condensed with one or two benzene rings;
• where X is an oxygen atom, a sulfur atom, a carbonyl group, or a sulfonyl group;
• and
• wherein the charge generating substance is an X-type metal free phthalocyanine.

A photoconductor for electrophotography, comprising:

• an electroconductive substrate;
• and
• a photosensitive layer which is a laminate formed on the electroconductive substrate and which includes a charge generating layer containing a charge generating substance, and a charge transporting layer containing a charge transporting substance;
• wherein the charge transporting substance consists of a diamine compound represented by a general formula (I) ##STR180## where R.sub.1 and R.sub.2, which are the same of different, each represent independently an alkyl group, an alkoxy group, or a halogen atom;
• where R.sub.3 and R.sub.4, or R.sub.5 and R.sub.6, combine together with a nitrogen atom to which they are bonded and form a monocyclic aromatic ring having a nitrogen atom as a heterto atom and being condensed with one or two benzene rings;
• where X is an oxygen atom, a sulfur atom, a carbonyl group, or a sulfonyl group;
• and
• wherein the charge generating substance is a bisazo pigment represented by a formula (IV) below ##STR181##
