Toner and process for production thereof

摘要

Disclosed is a toner obtained by coating surfaces of core particles including at least a binder resin having a carboxyl group and a coloring agent with successive coatings of a water-soluble crosslinking agent capable of crosslinking with a carboxyl group and a water-soluble polymer having a carboxyl group, which have been successively applied on the core particles and crosslinked with each other. The thus-formed toner is provided with a good harmony of favorable fixability represented by a low lowest fixable temperature and favorable storage stability represented by little aggregation after standing at 50° C. for 8 hours.
