Abstract

Provided is a method of producing a member for electrophotography capable of providing a high-quality electrophotographic image. The method of producing a member for electrophotography is a method of producing a member for electrophotography having an electro-conductive support, an elastic layer, and a surface layer, the method comprising: a first step of forming, on a surface of the elastic layer, a coat of a surface-layer coating liquid containing a hydrolyzed condensate of a hydrolyzable silane compound and a chelate titanium compound represented by the following general formula (2); and a second step of crosslinking the hydrolyzed condensate in the coat through cleavage of an epoxy group in the hydrolyzed condensate to form the surface layer:

First claim

What is claimed is:

a first step of forming, on a surface of the elastic layer, a coat of a surface-layer coating liquid containing a hydrolyzed condensate of a hydrolyzable silane compound represented by the following general formula (1) and a chelate titanium compound represented by the following general formula (2); and
a second step of crosslinking the hydrolyzed condensate in the coat through cleavage of an epoxy group in the hydrolyzed condensate to form the surface layer:

in the general formula (1), R 1 represents a hydrocarbon group represented by any one of the following general formulae (3) to (6), and R 2 to R 4 each independently represent a hydrocarbon group;
in the general formula (2), R 5 and R 6 each independently represent a linear or branched alkyl group having 1 or more and 20 or less carbon atoms, and R 7 to R 10 each independently represent a hydrogen atom, an alkyl group having 1 or more and 3 or less carbon atoms, or an alkoxy group having 1 or more and 3 or less carbon atoms;

in the general formulae (3) to (6):
R 11 to R 13 , R 16 to R 18 , R 23 , R 24 , R 29 , and R 30 each independently represent a hydrogen atom, an alkyl group having 1 or more and 4 or less carbon atoms, a hydroxyl group, a carboxyl group, or an amino group;
R 14 , R 15 , R 19 to R 22 , R 27 , R 28 , and R 33 to R 36 each independently represent a hydrogen atom or an alkyl group having 1 or more and 4 or less carbon atoms;
R 25 , R 26 , R 31 , and R 32 each independently represent a hydrogen atom, an alkoxyl group having 1 or more and 4 or less carbon atoms, or an alkyl group having 1 or more and 4 or less carbon atoms; and
n, m, l, q, s, and t each independently represent an integer of 1 or more and 8 or less, p and r each independently represent an integer of 4 or more and 12 or less, and “*” represents a bonding position with a silicon atom in the general formula (1).
