ABSTRACT:
A method and an apparatus for developing magnetic latent image, wherein a toner bearing member holding thereon a magnetic toner having an electric charge in a particular polarity is brought closer to a magnetic latent image bearing member, and an alternating electric field is acted across the magnetic latent image bearing member and the toner bearing member to cause the toner to reciprocate between these members to visualize the magnetic latent image by the magnetic force of attraction.
