    摘要: A toner includes a polyol-based resin having multiple hydroxyl groups in a molecular chain thereof in which a ratio of epoxy group to hydroxyl group is from 0.990 to 1.010. A stirring and transfer device satisfies 1000000≦α×β×γ≦16000000, wherein α represents a number of rotation per minute, β (mm) represents a pitch and γ (mm) represents a transfer path length of the stirring and transfer device. A temperature Tin (° C.) in a development device during stirring and transfer of a two component developing agent satisfies 3020 C.
