Therefore, after the toner image is transferred onto the recording material, the recording material may have static electricity
Also, when the recording material bearing the toner image is moved from the transfer unit to the fixing unit, static electricity may cause movement of the toner, resulting in disturbance in the formed image

Embodiment Construction
[0032] Hereinafter, exemplary embodiments of the present invention are described in detail with reference to the accompanying drawings.
[0033] Description of Entire Image Forming Apparatus
[0034] figure 1 A schematic configuration of an image forming apparatus 1 according to an exemplary embodiment is shown.
[0035] The image forming apparatus 1 includes a photosensitive drum 11 , an intermediate transfer belt 20 , a secondary transfer unit 30 , a fixing unit 50 , a controller 60 , a charge eliminating unit 70 , and a transport unit 80 . The photosensitive drum 11 serves as an image carrier rotatable in a direction indicated by an arrow A. As shown in FIG. The intermediate transfer belt 20 serves as a transfer material rotatable in the direction indicated by the arrow B, and the toner images composed of various color components formed on the photosensitive drums 11 are sequentially transferred (primary transfer) onto the intermediate transfer belt and remain on the int...

The present invention discloses an image forming apparatus and a charge eliminating device. The image forming apparatus includes a toner image forming unit that forms a toner image, a transfer unit that transfers the toner image formed by the toner image forming unit onto a recording material, a fixing unit that fixes the toner image transferred by the transfer unit onto the recording material to the recording material, a transport unit that includes a rotary member that transports the recording material from the transfer unit to the fixing unit and a recording material guiding portion that has first protruding portions extending along a recording material transport direction, and a charge eliminating unit that is disposed between the transfer unit and transport unit and eliminates charge on the recording material. The charge eliminating unit includes a first charge eliminating portion having pointed projections, and a second charge eliminating portion that is disposed on a downstream side of the first charge eliminating portion in the recording material transport direction and is disposed to be out of contact with the recording material.
Description
technical field [0001] The present invention relates to an image forming device and a charge eliminating device. Background technique [0002] In an image forming apparatus using an electrophotographic system such as a copier and a printer, a drum-shaped photoreceptor is uniformly charged and exposed to light controlled based on image information, thereby forming an electrostatic latent image on the photoreceptor. Then, the electrostatic latent image is converted into a visible image (toner image) using a toner, the toner image is transferred onto a recording material, and the transferred image is fixed by a fixing device to form an image. [0003] Unexamined Japanese Patent Application Publication No. 2008-76680 discloses an image forming apparatus. The image forming apparatus functions as a copier capable of forming images on both sides of recording paper by forming an image on a first side of the recording paper and then forming an image on a second side of the recording...
