Developing device collecting developer flowed from developing case by filter and applying vibration to filter to shake off developer and image forming apparatus including the same

摘要

A developing device includes a contact member and a developing adhesion member. The contact member is provided to an air releasing part communicating an inside and an outside of a developer case storing a developer containing a toner, in a condition being contactable with an agitating member agitating and conveying the developer in the developing case. The developing adhesion member is supported by the contact member and is configured to collect the developer within air flowing from the inside to the outside of the developing case and to receive vibration caused by agitating and conveying operations of the agitating member through the contact member.
