Title (EN) IMAGE-FORMING DEVICE
(FR) DISPOSITIF DE FORMATION D'IMAGE
(JA) 画像形成装置
Abstract:
(EN) Provided is an image-forming device that is capable of stabilizing the behavior of a transfer material during conveyance, while suppressing toner image distortion caused by electrical discharge. An image-forming device 100 is configured so that, during the period from when the leading end, in the conveyance direction, of a transfer material P has traveled a prescribed distance from a transfer unit N2 toward a fuser unit N3 until the trailing end, in the conveyance direction, of the transfer material P passes over the transfer unit N2, a controller 50 applies, from a power source E3 to a charge-removing member 5, a voltage at which the value of the electrical potential of the charge-removing member 5 is the same polarity as the charge polarity of the toner on an image carrier 1, and is larger than during the period from when the leading end, in the conveyance direction, of the transfer material P passes over the transfer unit N2 until the leading end has traveled the prescribed distance.
(FR) L'invention concerne un dispositif de formation d'image qui est capable de stabiliser le comportement d'un matériau de transfert pendant le transport, tout en supprimant une distorsion d'image de toner provoquée par une décharge électrique. Un dispositif de formation d'image (100) est configuré de telle sorte que, pendant la période à partir du moment où l'extrémité avant, dans la direction de transport, d'un matériau de transfert (P) a parcouru une distance prescrite d'une unité de transfert (N2) à une unité de fusion (N3) jusqu'à ce que l'extrémité arrière, dans la direction de transport, du matériau de transfert (P) passe sur l'unité de transfert (N2), une unité de commande (50) applique, depuis une source d'alimentation (E3) à un élément de suppression de charge (5), une tension à laquelle la valeur du potentiel électrique de l'élément de suppression de charge (5) a la même polarité que la polarité de charge du toner sur un support d'image (1), et est plus grande que pendant la période à partir du moment où l'extrémité avant, dans la direction de transport, du matériau de transfert (P) passe sur l'unité de transfert (N2) jusqu'à ce que l'extrémité avant ait parcouru la distance prescrite.
(JA) 放電によるトナー像の乱れを抑制しつつ、転写材の搬送挙動を安定させることのできる画像形成装置を提供する。 画像形成装置100は、制御部50が、転写材Pの搬送方向の先端が転写部N2から定着部N3へと所定距離移動してからその転写材Pの搬送方向の後端が転写部N2を通過するまでの間に、その転写材Pの搬送方向の先端が転写部N2を通過してから上記所定距離移動するまでの間の除電部材5の電位よりも像担持体1上のトナーの帯電極性と同極性側に大きい電圧を、電源E3から除電部材5に印加させる構成とする。
