Problems solved by technology

Therefore, there is a problem that the electric field formed by the static-eliminating needles does not necessarily play a proper role in separating the toner image from the peripheral surface of the photosensitive drum, resulting in leakage of the electric field to the transfer member or the photosensitive drum, and the desired effect cannot be obtained.
[0011] Furthermore, the device of D3 is only provided with a diaphragm with insulating material properties between the destaticizing needle and the transfer member, so it cannot obtain the expected Effect

Embodiment Construction

[0021] First, a printer as an example of the image forming apparatus of the present invention will be described with reference to FIG. 1 . FIG. 1 is a front sectional view schematically showing an internal structure of an embodiment of a printer. As shown in the figure, the printer 10 includes, installed in the main body 11 of the apparatus: a paper storage unit 12 for storing paper P for printing processing; Image transfer processing is performed on each sheet of paper P; the fixing unit 14 performs fixing processing on the paper P that has been transferred in the image forming unit 13, and the paper output device installed on the top of the device main body 11 The unit 15 discharges the paper P subjected to the fixing process in the fixing unit 14 .

[0022] A predetermined number (one in this embodiment) of paper cassettes 121 are provided in the paper storage unit 12 , and can be freely inserted into and removed from the apparatus main body 11 . At the upstream end of th...

Abstract

The present invention provides an image forming device, which includes: an image carrier forming a toner image and rotating in a circumferential direction; a transfer member arranged opposite to the surface of the image carrier to electrostatically transfer the toner image to the paper that passes through the opposite parts of the image carrier and the transfer member; the static remover generates an electric field for removing the charge on the paper, and separates the paper on which the toner image is transferred from the image carrier; and a conductive member disposed between the static eliminator and the transfer member.

Description

technical field [0001] The present invention relates to an image forming apparatus for transferring a toner image onto paper, and in particular to an improvement of a static eliminator for performing a charge-removing treatment on transferred paper. Background technique [0002] The basic configuration of an image forming apparatus is usually to arrange a charger, an exposure device, a developing device, a transfer member, and a cleaning device around a photosensitive drum (image carrier) driven to rotate about an axis. [0003] The photosensitive drum is driven to rotate around its axis, and a high voltage is applied from the charger to form a uniform charge on the peripheral surface of the photosensitive drum. Then, an electrostatic latent image is formed on the peripheral surface of the photosensitive drum on which the uniform charge is formed by irradiating light rays based on image information from an exposure device to the peripheral surface of the photosensitive drum....
