ABSTRACT:
A development apparatus includes a developer guide member in a position on an upstream side of a blade in a rotating direction of a developing roller, where the developer guide member does not come into contact with the developing roller. The developer guide member is formed of an elastic body or an elastic foam body. The developer guide member prevents toner which is regulated by the blade from flowing upward from the blade, and allows the toner to efficiently flow underneath the blade. Therefore, with an image forming apparatus using toner as a nonmagnetic single-component developer, it is possible to obtain high-density image quality. It is also possible to provide a development apparatus, in a simple and inexpensive construction, which decreases deterioration of the toner and the apparatus with time.
