Abstract
A hot melt ink includes at least one wax, at least one coloring material, a first resin having a softening point ranging from room temperatures to 100.degree. C., and a second resin having a softening point ranging from 50.degree. C. to 150.degree. C. and higher than the softening point of the first resin. The hot melt ink has an appropriate softening point and high light transmittance while maintaining fixing property and appropriate viscosity by combining a resin with a relatively low molecular weight and a resin with a relatively high molecular weight.
