Abstract
An image forming method using toner comprising toner particles having a core-shell structure comprising a core particle incorporating a viscous material and a shell layer covering the above core particle is disclosed. The method comprises steps of a toner image forming step on a dielectric drum; a first pressure applying step in which the shell layer of the toner particles forming the toner image is subjected to a preliminary break treatment by a first pressure roller, which is arranged in contact with the dielectric drum; and a transfer/fixing step in which a toner image made by the toner particles which have been subjected to a preliminary break treatment by the first pressure applying step is transferred and fixed to an image support by a second pressure roller which is arranged in contact with the dielectric drum.
