Abstract:
A toner for use in electrophotography comprising toner particles, each toner particle comprising a resin, a colorant, a fluidity-imparting agent and a volatile organic component which is in an amount of 100 ppm or less per unit amount of said toner particles, and having an average spherical degree in a range of 100 to 150, which is calculated from a spherical degree (SD) of each toner particle defined by formula (I):SD=25.pi.L.sup.2 /S (I)where L is a maximum length of a projected cross-sectional image of each toner particle, and S is an area of the projected cross-sectional image of each toner particle, wherein said toner particles have a softening point of 50.degree. C. or more and a flow-initiating point of 110.degree. C. or less.
