In a development apparatus of the hybrid method using a component
developer, a development apparatus and a development method are provided
that prevent the reduction of density or the occurrence of residual
images (ghost images) and can carry out good image forming over a long
period of time. A development apparatus has the feature that the surfaces
of the toner supporting member and the developer supporting member move
in a mutually opposite direction at the part where they are opposite to
each others. The development apparatus further employs an electric field
in the closest part applied in a direction to recover the toner from the
toner supporting member to the developing supporting member, wherein the
magnitude of the electric field is in the range from 2.5.times.10.sup.6
V/m to 5.times.10.sup.6 V/m. The developer of the development apparatus
is such that its share (PD) in the space of the closest part of the
opposing portion satisfies the following relationship:
0.09.ltoreq.PD.ltoreq.650.times.Dss.
