Abstract
An electrophotographic photoconductor including a sequentially-provided conductive substrate, an undercoat layer, and a photosensitive layer. Photosensitive layer is a negatively-charged stacked type including a charge generation layer and a charge transport layer. Undercoat layer contains a resin binder and a first filler, the first filler including a zinc oxide particle surface-treated with an N-acylated amino acid or an N-acylated amino acid salt, and the charge generation layer containing an adduct compound of titanyl phthalocyanine and butanediol.
Claims7
An electrophotographic photoconductor comprising:
- a conductive substrate;
- and
- an undercoat layer and a photosensitive layer sequentially provided on the conductive substrate, wherein
- the photosensitive layer is a negatively-charged stacked type having a charge generation layer and a charge transport layer, the charge generation layer containing an adduct compound of titanyl phthalocyanine and butanediol;
- the undercoat layer contains a resin binder and a first filler, the first filler containing a zinc oxide particle surface-treated with an N-acylated amino acid or an N-acylated amino acid salt;
- the undercoat layer further contains a second filler, the second filler containing a titanium oxide particle surface-treated with an aminosilane compound;
- and
- an amount of the zinc oxide particle surface-treated with the N-acylated amino acid or the N-acylated amino acid salt thereof, with respect to a total amount of fillers including the first filler and the second filler is 20% by mass or more and 80% by mass or less.
