Title: ダイレクト印刷装置
IPC: G03G15/05
Filed: 1999-12-16
Abstract: (57)【要約】
本発明は、コンピュータが作成した画像情報を、帯電粒子を粒子キャリア（３３）からプリントヘッド構造（５）の孔を介して背面電極（１２）へと選択的に移動させる静電界のパターンに変換し、帯電粒子は画像受取基板（１）上に付着させるダイレクト印刷装置に関する。プリントヘッドの孔を通過するトナーの流れを改善し、孔の中や周りへのトナーの散乱や付着を減少させるために、各孔に対応する電極には、第２の面より面積が大きい第１の面が形成される。これにより、孔に臨む電極端面は粒子の孔に対して流出入させる漏斗の役割をする。さらに、電極端縁の周りの電界パターンがより均一になり、電界の周辺効果による電気的故障の危険性がかなり減少する。このことにより、制御電極へ引かれるトナーの量が減少し、トナー粒子の散乱も大幅に制限される。
