<p>PROBLEM TO BE SOLVED: To provide a carrier which can realize high durability and high productivity although the carrier is a resin coated carrier which can be manufactured at a low cost with high safeness for the environment. SOLUTION: The carrier has a coating layer on the carrier core, and the coating layer consists of polyoxyalkylene-modified polyorgano silsesquieoxane resin having amino groups, polyoxyalkylene groups and alkoxy groups in one molecule expressed by general formula. In formula, R1 is a monovalent hydrocarbon residue which may be substituted with halogen atoms, R2 is a 1-4C alkyl group, R3 is a 1-4C alkyl group and/or alkoxy group, X is -(CH2)3- or -(CH2)3 NH(CH2)2- group, R4 is 2-4C alkylene group, q is a number satisfying 5<=q<=30, Y is an alkyl ether, alkyl phenylether, methacryloyl and/or acryloyl group, n is a number from 1 to 50 and m+p ranges from 2 to 150.</p> |
