Claim:
A toner comprising: a binder resin, a colorant, a releasing agent and a polyester resin, the toner having an average circularity of 0.950 or more, wherein: (a) the polyester resin contains at least, as a main component, a crystalline polyester component obtained by subjecting a monomer composition containing, as main components, an alcohol selected from aliphatic diols each having 2 to 22 carbon atoms and a carboxylic acid selected from aliphatic dicarboxylic acids each having 2 to 22 carbon atoms to a polycondensation reaction; and (b) a region having a lamellar structure formed of the crystalline polyester component and present at a surface layer of the toner, wherein a ratio (Wc/Pc) of a content mass (Wc) of the releasing agent to a content mass (Pc) of the crystalline polyester component is 0.5 to 8.0.
