Abstract
An apparatus and method for inversion development control for an image forming device in which toner and carrier particles are prevented from scattering unnecessarily. Scatter prevention is performed by gradually changing both a bias voltage application to a development roller and a surface voltage application to a photosensitive drum of the image forming device. Scatter prevention is also performed by gradually changing both a bias voltage application to a development roller and an exposure light quantity that the photosensitive drum is subjected to by an exposing rod lens array of the image forming device.
