Claims (3)
- 現像器を含む画像形成プロセスユニットと、該プロセスユニットに関連付けて配置されるトナーの収容部とを繋いでトナーの搬送系が構成される画像形成装置であって、
上記トナーの搬送系は、相互に接離可能に接合されるトナーの受渡し部を含み、該受渡し部の近傍部位の表面には漏出したトナーを捕捉する捕捉部材が添装され、
上記画像形成プロセスユニット及び/若しくはトナーの収容部は、装置本体に対して手前側より奥側に着脱可能に装着され、
上記トナーの受渡し部の接合状態は、上記装着の際に該装着方向に移動するトナーの受入口が静止状態のトナーの排出口の下に重なることによって確立され、
上記トナーの排出口の下面及び上記トナーの受入口の上面には、該排出口及び受入口を開閉するシャッター部材が設けられ、
上記装着の際、装着方向に沿った押圧作用を受けて、受入口のシャッター部材が開き切った後、排出口のシャッター部材が開き、装着が完了したとき、上記排出口及び受入口が上下に整合して上記接合状態が確立されるよう構成し、
上記捕捉部材は、上記トナーの受入口の近傍に添装され、かつ、上記装着方向の奥側にあって、上記接合状態に至る過程で上記トナーの排出口の下部を通過する部分を含んでいることを特徴とする画像形成装置。 - 請求項1に記載の画像形成装置において、
前記捕捉部材は、トナー粒子を取り込み得る多数のミクロコアを備えた多孔部材からなることを特徴とする画像形成装置。 - 請求項1又は2に記載の画像形成装置において、
前記トナーの受渡し部は、前記装着方向手前側に位置することを特徴とする画像形成装置。
