Image forming method using two pressure steps

An image forming method using a toner comprising toner particles having a core-shell structure comprising a core particle incorporating a viscous material and a shell layer covering the core particle, wherein 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, a pressure strength of the first pressure roller to the dielectric drum is 1 to 10 kg/cm in a linear pressure;
• 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.
