Toner resin composition and toner

摘要

A toner resin composition is provided which is superior in anti-offset properties, anti-smearing properties and low temperature fixability, has superior image stability even when the copier is used for a long duration of time, and is not prone to aggregation. The toner resin composition mainly comprises a vinyl-type copolymer(s) which contains a low polymer component which is cross-linked using a cross-linking agent comprising diacrylate or dimethacrylate obtained from a diol which has a linear chain with a carbon number of 5 or more with no branches, or a branch(es) with a carbon number of 1 or less and has a peak molecular weight in the molecular weight distribution curve of from about 4x103 to 8x104 and a non-cross-linked high polymer component which has a peak molecular weight in the molecular weight distribution curve of from about 1x105 to 4x106, wherein said vinyl-type copolymer mainly comprises styrene-type monomers with (meth)acrylic ester monomers and/or other vinyl-type monomers as structural units.
