ABSTRACT:
An image forming method comprises the step of a) developing an electrostatic latent image with toner; b) transferring the developed image onto a recording material to obtain a toner image on the recording material; and c) passing the recording material with the toner image between a first member and a second member positioned against the first member to fix the toner on the recording material, a silicone oil having been coated on the surface of at least one of the members, the toner containing a blend of a cross-linked polyester resin and a styrene/acryl resin, wherein the MEK insoluble component content of the toner is 40 to 65 weight %, the MEK soluble component of the toner has a weight average molecular weight Mw of 5.times.10.sup.4 to 2.times.10.sup.5, a number average molecular weight Mn of 1.times.10.sup.3 to 2.times.10.sup.3 and Mw/Mn of 25 to 80, and the silicone oil is a fluorine-containing silicone oil having a structure unit represented by the following Formula (I): ##STR1##
