Abstract
An image forming method is disclosed, comprising (a) forming a toner image on an image forming body, (b) transporting the image forming body to a transfer region, (c) overlapping an image supporting body onto the image forming body, (d) radiating ultrasonic waves onto the image forming body and the image supporting body by an ultrasonic radiation means with applying an electric field between the image forming body and the image supporting body to transfer the toner image onto the image supporting body and (e) subjecting the toner image on the image supporting body to contact heat-fixing to fix the toner image, wherein a toner is comprised of toner particles containing a resin, a colorant and a releasing agent, and the toner particles exhibiting a coefficient of variation of shape factor of not more than 16% and a coefficient of variation of number particle size distribution of not more than 27%.
