PURPOSE:To obtain the carrier coated with a coating material having sufficient mechanical strength to wear and impact, etc., by coating the carrier with a crosslinking type modified alkoxy alkylated polyamide resin and forming the graft part constituting this polyamide resin of a polymer or copolymer contg. a specific unit component. CONSTITUTION:The carrier is coated with the crosslinking type modified alkoxy alkylated polyamide resin and the graft part constituting this polyamide resin is formed of the polymer or copolymer contg. the unit component expressed by formula I. In the formula I, R1 denotes a hydrogen atom or methyl group; R2, R3 denote a hydrogen atom, substd. or unsubstd. alkyl group, substd. or unsubstd. aryl group, which may be the same of different. R2, R3 may form a ring with each other. The carrier imparted with the various characteristics, such as wear resistance and mechanical strength to the resin is obtd. in this way. |
