Abstract

The embodiment of the invention solves a technical problem to provide a developer device reducing the scatter of a toner included in the developer device and an image forming apparatus. The developer device includes a housing receiving an developing agent, a developing roller configured to rotate within the housing and opposite to an image bearing body rotating outside the housing, and an air path having a first opening portion formed in the housing and a second opening portion opposite to the developing roller and formed at the downstream side of a rotation direction relative to the developing area of the developing roller.

Description

technical field [0001] Embodiments of the present invention relate to a developing device and an image forming apparatus using the developing device. Background technique [0002] In an image forming apparatus such as a copier or a printer, toner is scattered into the apparatus from a developing device constituting an image forming portion of the image forming apparatus. Scattered toner adheres to a charging charger or the like and causes failure. In order to reduce the scattering of the toner, it is necessary to take countermeasures such as providing a filter, a fan, and the like for recovering the scattered toner. Contents of the invention [0003] The technical problem to be solved by the invention [0004] The technical problem to be solved by the embodiments of the present invention is to provide a developing device for reducing scattering of toner contained in a developer, and an image forming apparatus using the developing device. [0005] Technical solutions to ...
