ABSTRACT:
A magnetic recording device includes a magnetic latent image on a latent image carrier and a developing device for moving a magnetic recording color microcapsule onto the magnetic latent image carrier, the microcapsule including a colored material covered with an outer wall and a magnetic material disposed on the outer wall. A transfer device transfers the colored material in the microcapsule on the latent image carrier onto a recording medium as the magnetic material disposed on the outer wall of the microcapsule substantially remains attracted to the magnetic latent image. A demagnetizing device demagnetizes the magnetic latent image on the latent image carrier, and a cleaner cleans off from the latent image carrier the magnetic material which substantially remained attracted to the magnetic latent image when the colored material was transferred onto the recording medium.
