Abstract:
Provided is an electrophotographic photoreceptor including: a conductive substrate; a single-layer type photosensitive layer that is provided on the conductive substrate; an inorganic protective layer that is provided on the single-layer type photosensitive layer; wherein layers that are interposed between the conductive substrate and the inorganic protective layer have a total thickness of 10 μm to 25 μm.

Claim (Index 9):
An electrophotographic photoreceptor for positive charging, comprising:\n a conductive substrate; an organic photosensitive layer that is provided on the conductive substrate; and an inorganic protective layer that is provided on the organic photosensitive layer, the inorganic protective layer including a Group 13 element and oxygen, wherein a sum of element composition ratios of the Group 13 element and the oxygen with respect to all elements constituting the inorganic protective layer is 0.70 or more, and the inorganic protective layer includes at least one combination of:\n a first region in which an element ratio (oxygen/Group 13 element) of the oxygen to the Group 13 element is 1.10 to 1.30; and \n a second region in which an element ratio (oxygen/Group 13 element) of the oxygen to the Group 13 element is 1.40 to 1.50 in this order on the organic photosensitive layer, \n wherein the second region is the upmost layer of the inorganic protective layer.
