| abstract |
The present invention provides a toner including: a toner mother particle; an amorphous fine particle; a monodisperse spherical silica; and a metal soap, wherein the amorphous particle has the same polarity as the toner mother particle, a volume mean particle size of 0.1 times or less that of the toner mother particle, and a work function larger than that of a cleaning blade of a developing device, wherein an average sphericity of the toner L 0 /L 1 is from 0.970 to 0.985, provided that L 1 represents a circumferential length (μm) of a projected image of the toner particle, and L 0 represents a circumferential length (μm) of a true circle having an area equal to that of the projected image of the toner particle. |
