Abstract: This invention relates to a single component magnetic tone containing an epoxy resin and a magnetic pigment, particularly iron oxide pigments, which have been treated with surface reactive coupling materials, selected from organic titanates and lechithin, which treatment results in a magnetic toner where the melt flow temperature of such a toner is below 110.degree. C., and preferably between about 90.degree. C. and 105.degree. C. Also described is a method for the development of magnetic images which involves causing the formation of a magnetic latent image on a magnetizable recording medium, developing the image with the above toner, followed by transferring the image to a suitable substrate, and subsequently permanently fusing the image to said substrate by heat.
