Abstract
Since a charge amount of a toner and a charge rise characteristic thereof are liable to be influenced by the change in temperature and humidity condition, the change in image density occurs in printing, and in particular, in high temperature and high humidity environment, inconveniences, such as image fogging, occur due to non-uniformity of the charge amount distribution. In a toner including toner particles obtained by dispersing a monomer composition containing a polymerizable monomer and a colorant in an aqueous medium to form droplets and polymerizing the polymerizable monomer in the droplets, the toner particles contain a polymer formed by a polymerization reaction of the polymerizable monomer and a metal compound having a vinyl group.
