| abstract |
An object of the present invention is to improve the low-temperature fixability that enables high-speed operation while maintaining the offset resistance, improve the pulverizability in the manufacturing stage, and improve the storability, as well as to improve the recording medium such as paper. An object of the present invention is to provide a toner having improved fixing strength and a method for producing the toner. The toner of the present invention is obtained by polymerization of a compound containing two or more isocyanate groups and a compound containing two or more active hydrogens that react with the isocyanate group, and has a main chain having a urethane bond or a urea bond. And a crystalline resin having compatibility with the polymer, having a number average molecular weight (Mn) of 1,500 to 20,000 at the stage of forming the toner, and a flow softening point (Tm). Is 80 to 150 ° C. [Selection diagram] None |
