Electrophotographic photoconductor and image forming apparatus

摘要

The present invention provides an electrophotographic photoconductor including an electrically conductive substrate, an intermediate layer, and a photosensitive layer that are formed on the electrically conductive support, the intermediate layer including first titanium oxide particles surface-treated with a first reactive organic silicon compound, second titanium oxide particles surface-treated with a second reactive organic silicon compound different from the first reactive organic silicon compound, and a binder resin. The first reactive organic silicon compound is methyl hydrogen polysiloxane. The second reactive organic silicon compound is a compound represented by the following general formula (1):
R—Si—(X)3  (1)
R represents a alkyl group having 1 to 10 carbon atoms substituted by at least one of acryloxy and methacryloxy groups or unsubstituted; and X represents an alkoxy group having 1 to 4 carbon atoms or a halogen atom.

1. An electrophotographic photoconductor comprising an intermediate layer, and a photosensitive layer that are formed on an electrically conductive support, the intermediate layer comprising:
first titanium oxide particles surface-treated with an inorganic oxide and a first reactive organic silicon compound, the first reactive organic silicon compound being methyl hydrogen polysiloxane; second titanium oxide particles surface-treated only with a second reactive organic silicon compound different from the first reactive organic silicon compound, the second reactive organic silicon compound being a compound represented by the following general formula (1):
R—Si—(X)3  (1)wherein R represents a alkyl group having 1 to 10 carbon atoms substituted by at least one of acryloxy and methacryloxy groups or unsubstituted; and X represents an alkoxy group having 1 to 4 carbon atoms or a halogen atom; and
a binder resin.
