ABSTRACT:
Disclosed is a toner image forming method, comprising steps of:
(1) forming a latent image on an image carrying member,
(2) developing said latent image with toner particles including a resin and a colorant so as to form a toner image, said toner particles having a volume average particle size of 5 to 10 .mu.m, and containing toner particles having particle sizes of not more than 5.04 .mu.m in 5 number.multidot.% to 60 number.multidot.%,
(3) transferring said toner image onto an image receiving material, and
(4) fixing said transferred toner image on said image receiving material, said fixing steps comprising
(a) passing said image receiving material between a movable fixing member and a rotatable pressure applying member each having a surface facing each other,
(b) heating said toner image by a heater incorporated in said fixing member, and
(c) coating the surface of said fixing member facing said pressure applying member with a fluorine-containing silicone oil by a coating roller, said fluorine-containing silicone oil having a structure unit represented by Formula I: Formula I ##STR1## wherein X represents an alkyl group having 1 to 4 carbon atoms or an aryl group, Rf represents a fluoroalkyl group having 2 to 10 carbon atoms and n represents an integer of 1 to 4.
