PROBLEM TO BE SOLVED: To satisfy resolution and ink absorptiveness, and obtain high water resistance by containing a copolymeric saponified substance of diacetone acrylamide-fatty acid vinyl ester and one or more kinds selected from a hydrazine compound and diamine compound in the carrier base body. SOLUTION: Contained in a carrier base body and/or on the surface thereof are a copolymeric saponified substance (DAVES) of diacetone acrylamide-fatty acid vinyl ester and one or more kinds selected from a hydrazine compound and diamine compound. A content of the diacetone acrylamide unit of DAVES is preferable to be about 0.1-15 mol.%, and more preferable to be about 0.5-10 mol.%. A use quantity of one or more kinds selected from a hydrazine compound and diamine compound is preferable to be in the range of about 0.5-50 pts.wt. relative to about 1-30 pts.wt., and more preferable to be in the range of about 1-30 pts.wt. |
