A toner composition including toner particles including at least a binder resin; and a colorant, wherein the toner composition satisfies at least one of the following relationships (1) and (2): <?in-line-formulae description="In-line Formulae" end="lead"?>B<=14 when 155<A<=180; and<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>B<=0.6A-79 when 145<=A<=155, (1)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein A represents a shape factor SF-1 of the toner composition and B represents a content of toner particles having a particle diameter not greater than 3 mum; and <?in-line-formulae description="In-line Formulae" end="lead"?>B<=14 when 0.920<=A'<=0.950; and<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>B<=394-400A' when 0.950<A'<=0.965 (2)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein A' represents an average circularity of the toner composition and B represents a content of toner particles having a particle diameter not greater than 3 mum.
