<p>PURPOSE:To provide a toner used for an image forming system in which an untransferred toner is recovered and reutilized, maintaining high image density over a long period of time and not causing fog or scattering and to provide an image forming method. CONSTITUTION:This toner contains at least a bonding resin and a colorant, has 4-11mum wt. average particle diameter, contains 3-15number% toner particles having 2.00-4.00mum particle diameter and 8-19-number% toner particles having 4.00-5.04mum particle diameter in the particle size distribution and satisfies <=30 coefft. B of variation of wt. distribution represented by an equation B=Sw/D4X100 (where, Sw is the standard deviation of wt. distribution and D4 is wt. average particle diameter).</p> |
