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.

Abstract: An image forming process is disclosed, comprising the steps of passing an image recording material comprising a support having thereon an image formed of a toner containing a resin and a colorant, through a fixing member comprised of a pair of a heating roller and a pressure roller, and heat-fixing the image to the support by the fixing member, wherein the thus-formed image has a standard glossiness of 17 to 37.

Abstract: A fixing method comprises the step of passing a recording material with a toner image between a heat fixing member and a pressure applying member to fix the toner onto the recording material, a silicone oil being coated on the surface of the heat fixing member, wherein the toner contains a binder resin and a low molecular weight polyolefin, and the silicone oil is a fluorine-containing silicone oil having a structure unit represented by the following Formula (I): ##STR1## wherein X represents a saturated hydrocarbon group having 1 to 4 carbon atoms or an aryl group; R.sub.f represents a fluoroalkyl group having 2-10 carbon atoms; and n represents an integer of 1 to 4.

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.

Abstract: A toner for developing an electrophotographic image and a method for forming an electrophotographic image using the toner. The toner comprises a binder and a colorant, in which a volume average diameter of the toner particles, Dv in .mu.m, and a storage modulus at 170.degree. C. thereof, G'.sub.170 in dyne/cm.sup.2, satisfy the following relation;-(2/15)Dv+3.5.ltoreq.log G'.sub.170 .ltoreq.-(3/15)Dv+5.5.In the method, an electrophotographic image is developed by the above-mentioned toner and fixed by a fixing roller covered with a surface layer comprising a fluorine-containing resin.

Abstract: A resin coated carrier for developing an electrostatic image is disclosed. The carrier coating layer comprises a resin copolymerized of at least three fluorinated vinyl monomers. The carrier is useful for developing a negative charged electrostatic image formed on an organic photoreceptor.

Abstract: A developer for electrophotography is disclosed. The developer comprises a carrier comprising magnetic particles being coated with a fluororesin in which an alkali salt of a fatty acid is contained in an amount of from 0.05 to 0.5% by weight of said carrier, and a toner comprising a colored particle comprising a colorant and a reaction product of a styrene-acryl copolymer having carboxyl groups with a multivalent metal compound, and an inorganic particle containing an ammonium salt-modified polysiloxane. The developer is excellent in the reproducibility of fine line, the density uniformity of solid image and the fine line-reproducibility in copies formed by successive generations and the durability.
