Description
［態様Ｄ］
態様Ｄは、態様Ｃにおいて、前記サブユニット保持体の前記押し込み方向の下流端よりも下流側で駆動力を受ける駆動受け部（例えば、入力カップリング１３１）と、前記駆動受け部によって受けられた駆動力を前記サブユニット保持体の前記押し込み方向の上流端よりも上流側に伝達する第１駆動力伝達手段（例えば、駆動シャフト１３０）と、前記第１駆動力伝達手段の駆動力を、複数の前記クリーニングサブユニットにおけるそれぞれの前記クリーニング部材に伝達する第２駆動駆動力伝達手段（例えば、第１〜３駆動伝達部１４６ａ〜ｃ）とを設けている。
これによれば、上記実施形態について説明したように、クリーニングサブユニットの押し込み方向上流側に第２駆動駆動力伝達手段という駆動系を配置することができ、クリーニングサブユニットを押し込み方向上流側に引き抜くのに有利な構成をとることができる。さらに、クリーニングバイアスを外部から受ける電極を押し込み方向下流側に配置し、第２駆動駆動力伝達手段を押し込み方向上流側に配置することで、電極と第２駆動駆動力伝達手段とを近づけないレイアウトを実現することができる。これにより、駆動伝達系の回転軸等に金属製の部材が存在する場合、この金属製の部材と電極との間での放電の発生を回避できる。
[Aspect D]
Aspect D, in embodiments C, the driving force receiving portion for receiving a driving force in the downstream side of the push-in direction of the downstream end of the sub-unit holding body (for example, input coupling 131), received by the drive Do受 only portion First driving force transmission means (for example, driving shaft 130) for transmitting the generated driving force to the upstream side of the upstream end in the pushing direction of the subunit holding body, and the driving force of the first driving force transmission means. Second drive driving force transmission means (for example, first to third drive transmission units 146a to 146c) that transmit to the cleaning members of the plurality of cleaning subunits are provided.
According to this, as described in the above embodiment, the drive system called the second drive driving force transmitting means can be arranged upstream of the cleaning subunit in the pushing direction, and the cleaning subunit is pulled out upstream in the pushing direction. It is possible to adopt an advantageous configuration. Further, the electrode that receives the cleaning bias from the outside is arranged downstream in the pushing direction, and the second driving driving force transmitting means is arranged upstream in the pushing direction, so that the electrode and the second driving driving force transmitting means are not brought close to each other. Can be realized. Thereby, when a metal member is present on the rotating shaft of the drive transmission system, it is possible to avoid the occurrence of discharge between the metal member and the electrode.
