Abstract
A thermomagnetic recording apparatus, for example, facsimile receiver wherein the surface of a magnetic drum which is uniformly coated with a magnetic material is uniformly magnetized, the magnetized surface is locally heated to a temperature of at least a Curie point in accordance with facsimile signals by means of a thermal recording head, to reduce the coercise force and to invert the polarity of the magnetization, thereby forming a magnetic latent image, and the magnetic latent image is developed with magnetic toner.
