Claims (3)
- シート材の搬送方向に間隔をあけて並設した複数の帯状電極からなる複数の群を、各群の電極をシート材の搬送方向に交互に配置することでシート材の搬送方向に交互に配置するとともに、シート材の搬送方向に交互に配置した複数の群により構成された電極群をシート材の搬送方向と直交する幅方向に3以上並設した固定子と、
前記固定子の各電極群のそれぞれの群毎に異なる電圧を印加するための電源と、
前記電源から前記固定子の各電極群のそれぞれの群毎に印加する前記異なる電圧を切り替え制御する制御手段と、を有し、
前記シート材の搬送方向に交互に配置した各群に印加する前記異なる電圧を前記電極の並び方向に切り替えることでシート材を搬送し、前記電圧の切り替えタイミングを前記シート材の幅方向に並設した電極群毎に変更することで前記シート材の搬送速度を幅方向において異ならせてシート材を回転移動することを特徴とするシート材搬送装置。 - シート材の傾き角度を検知する傾き角度検知手段を有し、前記傾き角度検知手段の検知結果に応じて前記シート材の幅方向に並設した電極群毎に前記電圧の切り替えタイミングを変更して前記シート材の搬送速度を幅方向において異ならせて、前記シート材の傾きを補正するよう前記シート材を回転移動することを特徴とする請求項1に記載のシート材搬送装置。
- シート材に画像を形成する画像形成装置において、シート材を搬送するシート材搬送装置として前記請求項1又は2に記載のシート材搬送装置を有することを特徴とする画像形成装置。
