Abstract: An image forming apparatus includes a plurality of image forming portions, an intermediate transfer belt, a primary transfer member, a secondary transfer roller, a counter roller, and a charge eliminating device. The counter roller is pressed against the secondary transfer roller via an intermediate transfer belt to thereby form a secondary transfer nip portion. The charge eliminating device includes a charge eliminating needle that is disposed with an end part thereof pointing to a downstream side in a conveyance direction of the recording medium, and that is grounded, and a charge eliminating needle protection cover that has a guide surface that is opposed to the recording medium having passed through the secondary transfer nip portion, and that maintains a constant interval between the recording medium and the charge eliminating needle, and eliminates residual charge on the recording medium having passed through the secondary transfer nip portion.

Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

Abstract: A cleaning device cleans a conveyance face of a conveyance member conveying a sheet. The cleaning device includes a delivery roller, a pressure roller, a fixed roller and a winding roller. The delivery roller supports a web roll that a belt shaped web is wound into a roll. The pressure roller brings the web delivered from the web roll into pressure-contact with the conveyance face. The fixed roller keeps an extending angle of the web passed from between the conveyance member and the pressure roller constant. The winding roller winds the used web passed the fixed roller into a roll.

Abstract: A transferring device includes a conveying belt, a transferring roller, a stretching roller and a guide member. The conveying belt comes into contact with an image carrier carrying a toner image and conveys a sheet via a contact position to the image carrier. The transferring roller takes applying of voltage with a reversed polarity to a charged polarity of the toner forming the toner image and transfers the toner image carried on the image carrier onto the sheet at the contact position. The stretching roller stretches the conveying belt at a downstream side from the contact position in a conveying direction of the conveying belt and at a separation position of the sheet separated from the conveying belt. The guide member is arranged at a position facing to the sheet conveyed from the stretching roller to a fixing device to take applying of the voltage with the reversed polarity.

Abstract translation: 转印装置包括输送带，转印辊，拉伸辊和引导构件。 传送带与承载调色剂图像的图像载体接触，并且经由接触位置将片材传送到图像载体。 转印辊以相反极性的电压施加形成调色剂图像的调色剂的带电极性，并将承载在图像载体上的调色剂图像转印到接触位置的片材上。 拉伸辊在输送带的输送方向上的接触位置的下游侧和从输送带分离的纸张的分离位置处延伸输送带。 引导构件布置在面向从拉伸辊传送到定影装置的片材的位置以施加相反极性的电压。
