A development apparatus using a hopping method and an image formation
apparatus including the development apparatus are disclosed. The
development apparatus includes a toner supporting object for supporting
and conveying a toner by a movement of the toner supporting object, while
the toner is hopping on a surface of the toner supporting object by an
electric field; a regulating member made of a flexible material for
constituting a toner thickness regulation position; a latent image
supporting object for supporting a latent image; and a development
position, which is a position of the toner supporting object, that
counters the latent image supporting object; wherein the toner is
conveyed through the regulation position to the development position
where the toner is adhered to the latent image, and wherein one end of
the regulating member is supported, and the other end contacts the toner
supporting object.
