In the image forming process of the present invention wherein a toner is fixed
on an electrophotographic image-receiving sheet using a belt fixing and smoothing
device, the relationship among the temperature of a heating and fixing roller,
the melting point of a toner wax, and the glass transition point of a toner binder,
the relationship among the temperature of a heating and fixing roller, the melting
point of a wax in the image-receiving layer, and the glass transition point of
a binder in the image-receiving layer, and the relationship between the polar components
of surface free energy of the toner-image-receiving layer before and after image
fixing are optimized. The present invention is to prevent offset in the toner and
the toner-image-receiving layer of the electrophotographic image-receiving sheet
upon releasing of the belt and to avoid deterioration in image quality especially
in operation over the long run.
