Method for fusing developed image

In an imaging process which comprises the steps of forming a liquid toner image including pigmented thermoplastic polymer particles and a liquid carrier on an imaging surface, transferring the image to a substrate and fusing and fixing the substrate-supported liquid toner image by the application of heat from surface of an elastomer-coated first roller thereto, said substrate being transported through a nip defined by a portion of the surface of said first roller facing a surface of the substrate supporting the image and a portion of surface of a second roller, wherein, in the absence of carrier liquid, that portion of the liquid toner which is non-volatile, has a viscosity of not less than about 2.times.10.sup.6 centipoise at a temperature of about 121.+-.1.degree. C.,

• the improvement comprising:
• pre-selecting at least the following conditions, namely, the temperature at which the fusing and fixing is effected, the rate of transport of the substrate, and the properties of the liquid carrier, such that less than about half of the liquid carrier present in the transferred image is removed during fusing and fixing.
