<P>PROBLEM TO BE SOLVED: To provide a positive charging property control resin capable of imparting charging property of the same polarity as that of a toner to electrophotographic functional parts which come into contact with the toner and capable of forming a cured layer on a surface. <P>SOLUTION: The positive charging property control resin is a crosslinked material of a copolymer obtained by polymerizing a monomer composition including a hydroxyl group-containing monomer represented by formula (1) and an amino group-containing monomer represented by formula (2). In the formulae, X represents H or methyl group; Y represents a 2-6C alkylene group; Z represents O or NH; R<SP>1</SP>represents a 1-7C divalent organic group; and R<SP>2</SP>and R<SP>3</SP>each represents H and a 1-20C organic group or they represent a 4-20C cyclic structure in which R<SP>2</SP>and R<SP>3</SP>bond chemically to each other or a 4-19C cyclic structure in which R<SP>2</SP>and R<SP>3</SP>bond chemically to each other and which contains at least one selected from N, S and O. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
