PURPOSE:To obtain toner having superior characteristic by constituting a toner for developing positively charged static image of a resin component comprising homopolymer of monomer expressed by the specified general formula or copolymer comprising the monomer and vinyl monomer. CONSTITUTION:Toner for developing positively charged static image is constituted of homopolymer of monomer expressed by the formula or copolymer of said monomer with vinyl monomer. In the formula, R1 is H, lower alkyl; R2 is lower alkyl, aryl, amino, or alkoxy; X is a group connecting C atom in the principal chain with P atom, such as -COOR-, -OR-, etc. Suitable vinyl monomer is styrene, acrylic ester, methacrylic ester, acrylonitrile, vinyl acetate, vinyl pyridine, etc. |
