A heat transfer model is developed to simulate temperature of paper in and outside fuser nip considering water evaporation and latent heat consumption in paper. The model is based on measuring temperature of paper using an experimental apparatus which presses two sheets of paper between two flat heated plates. In the experiment, it is found that in the inside of paper latent heat consumption starts and temperature elevation rate changes over 100℃, and in the outside of paper latent heat consumption is little. The model is developed to define temperature-rise coefficient and multiply it by heat flux of paper in heat equation. Caluculation results of temperature of paper heated in fuser nip in this model indicate agreement with experimental results, as well as in a model considering no water evaporation. It is suggested that the temperature of paper is nearly unaffected by the latent heat consumption in paper.
