Abstract

Provided is a coating agent having a polymerizable compound containing a hydroxyl group in the molecule, conductive inorganic particles whose surface is treated with a dispersing agent having a nitrogen atom in the molecule, and a solvent, in which when the interatomic distance between an oxygen atom of the hydroxyl group and the atom farthest away from the oxygen atom in the molecule of the polymerizable compound is represented by D1 and the interatomic distance between the nitrogen atom and the atom farthest away from the nitrogen atom in the molecule of the dispersing agent is represented by D2, D1 and D2 satisfy the relationship represented by the following formula (1). [(| D 1− D 2|)/ D 2]≦0.30  Formula (1)

Claims (18)

1. A coating agent comprising:

a polymerizable compound having a hydroxyl group in a molecule thereof,

a conductive inorganic particle coated with a dispersant having a nitrogen atom in a molecule thereof, and

a solvent,

wherein,

when an interatomic distance between an oxygen atom in the hydroxyl group and an atom farthest away from the oxygen atom in the molecule of the polymerizable compound is represented by D1

and an interatomic distance between the nitrogen atom and an atom farthest away from the nitrogen atom in the molecule of the dispersant is represented by D2, wherein

D1 and D2 satisfy a relationship represented by the following formula (1):

(| D 1− D 2|)/ D 2]≦0.30  (1).

2. The coating agent according to claim 1 , wherein the polymerizable compound is (meth)acrylate or urethane(meth)acrylate.

3. The coating agent according to claim 1 , wherein the dispersant is tertiary amine.

4. The coating agent according to claim 1 , wherein D1 and D2 satisfy a relationship represented by the following formula (2):

(| D 1− D 2|)/ D 2]≦0.24  (2).

5. The coating agent according to claim 1 , wherein the polymerizable compound is pentaerythritol triacrylate.

6. The coating agent according to claim 3 , wherein the dispersant is tri-n-octylamine.

7. A method for producing an electrophotographic member having a substrate and a resin film formed on the substrate comprising:

applying the coating agent according to claim 1 on the substrate to form a coating film; and then

curing the coating film.
