Abstract
Abstract An electrophotographic photosensitive body comprising a conductive support, a photoconductive layer thereon and a protective layer. The protective layer comprises a binder resin, an aromatic diamine and an organic halogen capable of producing a free halogen atom, such as iodoform, carbon tetraiodide, pentabromoethane, p-nitrotribromoacetophenone, trichloroacetophenone, tribromomethylphenylsulfone, bis(tribromomethyl)-sulfoxide, and p-bromobenzenedichlorosulfonamide.

Total Claims: 3
Claim 1
Independent Claim
178 words
An electrophotographic photosensitive body comprising a conductive support having provided thereon, in sequence, a photoconductive layer and a protective layer, said protective layer containing in a binder resin an aromatic amine compound wherein said compound is of the following general formula (I) or (II) an an organic halogen compound capable of producing a free halogen atom: ##STR6## wherein X 1 , X 2 , Y 1 , and Y 2 each is an alkyl group or a substituted or unsubstituted aryl group, R 1 and R 2 each is a hydrogen atom, an alkyl group containing 1-6 carbon atoms, or a halogen atom, and --(A)-- represents a member selected from the group consisting of Members (III)-(IX) wherein ##STR7## wherein Z 1 and Z 2 each is an alkyl group containing 1-6 atoms, or a substituted or unsubstituted aryl group, and R 3 is a hydrogen atom or an alkyl group containing 1-6 carbon atoms, ##STR8## wherein Ar represents a substituted or unsubstituted aryl group, ##STR9## wherein R 4 represents an alkyl group containing 1-6 carbon atoms and ##STR10##
Claim 2
Dependent Claim
178 words
An electrophotographic photosensitive body comprising a conductive support having provided thereon, in sequence, a photoconductive layer and a protective layer, said protective layer containing in a binder resin an aromatic amine compound wherein said compound is of the following general formula (I) or (II) an an organic halogen compound capable of producing a free halogen atom: ##STR6## wherein X 1 , X 2 , Y 1 , and Y 2 each is an alkyl group or a substituted or unsubstituted aryl group, R 1 and R 2 each is a hydrogen atom, an alkyl group containing 1-6 carbon atoms, or a halogen atom, and --(A)-- represents a member selected from the group consisting of Members (III)-(IX) wherein ##STR7## wherein Z 1 and Z 2 each is an alkyl group containing 1-6 atoms, or a substituted or unsubstituted aryl group, and R 3 is a hydrogen atom or an alkyl group containing 1-6 carbon atoms, ##STR8## wherein Ar represents a substituted or unsubstituted aryl group, ##STR9## wherein R 4 represents an alkyl group containing 1-6 carbon atoms and ##STR10##
Claim 3
Dependent Claim
38 words
The electrophotographic photosensitive body as described in claim 1, wherein said organic halogen compound capable of producing a free halogen atom is selected from the group consisting of iodoform, carbon tetraiodide, pentabromoethane, p-nitrotribromoacetophenone, trichloroacetophenone, tribromomethylphenylsulfone, bis(tribromomethyl)-sulfoxide, and p-bromobenzenedichlorosulfonamide.
