摘要： A fixing device includes a contact portion formed by making a part of an endless belt supported by a plurality of tension rollers contact a fixing roller having an elastic body applied thereon. The contact portion includes a contact point formed by making a pressure roller inside the endless belt bear against the fixing roller under pressure through the endless belt at an exit point of the contact portion. The fixing device also includes a braking device which brakes the transport of the endless belt at the contact point such that the endless belt at the point where the pressure roller bears against the fixing roller moves at a speed greater than the remaining portions of the endless belt.

摘要： A method for forming an image with a copying machine capable of both color copying and black-and-white copying is disclosed, in which a black toner contains at least a colorant and a resinous component having a weight average molecular weight (Mw) of from 25,000 to 80,000 and a number average molecular weight (Mn) of from 2,000 to 8,000, with a Mw/Mn ratio being not less than 10, and having an apparent melt viscosity of 1.times.10.sup.4 poise at a temperature between 115.degree. C. and 140.degree. C. as measured by a flow tester method, and the quantity of heat of fixing is varied between a B/W mode and a color mode.
