Abstract
The toner for electrophotography includes a polylactic acid type resin, a terpene-phenol copolymer, and at least one kind of wax. A melting point of at least one kind of the wax is equal to or less than a softening temperature of the terpene-phenol copolymer. It is preferable that a molar fraction of one of L-lactic acid unit and D-lactic acid unit with respect to a total lactic acid unit in the polylactic acid type resin is in the range between about 85 mol % and about 100 mol %. Also, it is preferable that the total amount of the wax in the toner is in the range between about 7-20% by weight with respect to toner particles.
