Abstract: Disclosed is a toner including: a toner particle including at least a resin, a coloring agent and a mold release agent, wherein an average value e of degree of circularity of the toner particle is within 0.935=e=0.982, a maximum endothermic peak temperature of the mold release agent exists within 85-98° C., the resin includes at least non-crystalline polyester and crystalline polyester, and a ratio a of multivalent carboxylic acid of trivalent or higher-valent and a ratio c of straight chain aliphatic dial are such that 12.5=a=46, 20=c=65, 0.25=a/c=1.52, the multivalent carboxylic acid of trivalent or higher-valent and/or the straight chain aliphatic dial constituting the non-crystalline polyester and/or the crystalline polyester.

Abstract: Disclosed is a toner, comprising: a noncrystalline polyester resin; a crystalline polyester resin; a release agent; and a coloring agent, wherein the toner has a domain matrix structure in which the matrix comprises the noncrystalline polyester resin and the domain comprises the crystalline polyester resin and the release agent, and wherein the crystalline polyester resin includes within the release agent.

Abstract: A set of a yellow toner, a magenta toner, a cyan toner and a black toner is disclosed. Each of the color toners contains a colored particle and cerium oxide particles, the colored particle containing an amorphous polyester resin, a crystalline polyester resin, a colorant and a releasing agent; and the yellow toner contains C.I. Pigment Yellow 74, the magenta toner contains C.I. Pigment Red 122 and C.I. Pigment Red 238, the cyan toner contains any one of C.I. Pigment Blue 15:1, C.I. Pigment Blue 15:2 and C.I. Pigment Blue 15:3, and the black toner contains carbon black and any one of C.I. Pigment Blue 15:1, C.I. Pigment Blue 15:2 and C.I. Pigment Blue 15:3.
