Abstract
An image forming apparatus includes a developer
layer former (3) which charges developer to have a predetermined
polarity in a developer unit (4) and forms a uniform
thin layer of the developer on a developer carrier (1), an ion
irradiator (6) which irradiates ions towards the developer on
the developer carrier (1) partly so as to form a reversely
charged latent image thereon in accordance with recording
signals (5), and a transfer unit (8) which transfers the part of
the developer on the developer carrier (1) corresponding to
the latent image onto a recording medium (9) directly.
