Abstract:
An image forming method, comprising the steps of:forming a color image on a support, said color image consisting of a plurality of color toners, each having a melting point or a softening point; heating the color image upon application of a pressure at a first temperature while the color image contacts a surface of a fixing member, said first temperature being not lower than the melting points or softening points of the plurality of color toners, wherein said pressure applied satisfies the following relationship: ((9/5)Ã—log&eegr;4/5)/15&gE;P&gE;((1/100)Ã—log&eegr;)/15, wherein P represents said pressure in a unit of 9.8Ã—100 N/m, and &eegr; represents melt viscosity of each of said color toners in a unit of centi-poise at said first temperature;cooling the color image to a second temperature lower than the melting points or softening points while the color image contacts the surface of the fixing member; and separating the color image from the fixing member during the cooling step, wherein the surface of the fixing member has a ten-point mean roughness not greater than 20 &mgr;m.
