摘要： A development apparatus and an image forming apparatus capable of minimizing deterioration of a carrier for a long time, even in a case of continuous formation of images of a smaller image area ratio. The charging of toner is assisted by using a developer composed of a mixture of toner and the carrier, to the surface of which is added a reverse polarity particle having a polarity reverse to that of a charged toner. Separation of the toner or reverse polarity particle of the developer prior to a process of development prevents the reverse polarity particle from being consumed in a developing area, whereby an effect thereof is maintained for a long time.

摘要： 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 2.5×106 V/m to 5×106 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≦PD≦650×Dss.
