Image forming method using toner

An image forming method comprising:

• forming a toner image on a support using a toner including toner particles which are prepared by a method including:
• dissolving or dispersing toner constituents comprising a binder resin containing at least a modified polyester resin reactive with an active hydrogen atom in an organic solvent to prepare a toner constituent liquid;
• dispersing the toner constituent liquid in an aqueous medium comprising a particulate resin to prepare an emulsion;
• reacting the modified polyester resin with a compound having an active hydrogen atom in the emulsion to subject the modified polyester resin to at least one of a crosslinking reaction and an extension reaction;
• and
• removing the organic solvent from the emulsion, and
• feeding the support bearing the toner image thereon through a nip between an endless toner heating member and a pressure roller to fix the toner image on the support, wherein the endless toner heating member is rotated while stretched by a fixing roller and a heat roller which comprises a magnetic metal and which is heated by electromagnetic induction, and wherein the pressure roller presses the support bearing the toner image to the endless toner heating member and the fixing roller at the nip,
• wherein the toner has a storage modulus G′ of from 700 Pa to 4300 Pa at 180° C. under a condition of 1 Hz in frequency, and
• wherein the toner has an average circularity of from 0.90 to 0.96.
