Image forming method

An image forming method comprising the step of:

• fixing a toner image formed with a toner comprising a releasing agent on a transfer material employing a contact-heating fixing device comprising a heating roller and a belt-shaped pressure body,
• wherein the heating roller is placed on an unfixed toner image side of the transfer material;
• the releasing agent comprises a 1st releasing agent component containing a monoester compound represented by the following Formula (1) and a 2nd releasing agent component containing a hydrocarbon compound having a branched chain structure;
• and the 1st releasing agent component has a content of 40-98% by weight, based on the total weight of the 1st releasing agent component and the 2nd releasing agent component:
• R1—COO—R2 Formula (1)
• wherein R1 and R2 each represent a hydrocarbon group with a main chain having 13-30 carbon atoms, that may have a substituent, or may not have a substituent, and R1 and R2 each may be identical or different.
