Abstract
Official abstract text for this publication.
An image forming system includes: an image forming apparatus configured to form an image on a recording medium; a post-processing apparatus configured to perform post-processing on the recording medium on which an image is formed by the image forming apparatus; a relay apparatus having a function of changing a transport speed of the recording medium on which an image is formed by the image forming apparatus to a transport speed of the post-processing apparatus and transporting the recording medium to a subsequent stage; and a charge eliminating apparatus configured to perform charge elimination on the recording medium that is charged, by reducing a charge amount of the charged recording medium, and the charge eliminating apparatus is provided at a stage that is after the relay apparatus and before the post-processing apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming system comprising: an image forming apparatus configured to form an image on a recording medium; a post-processing apparatus configured to perform first post-processing on the recording medium on which the image is formed by the image forming apparatus; a relay apparatus transporting the recording medium on which the image is formed by the image forming apparatus to a subsequent stage; and a charge eliminating apparatus configured to perform charge elimination on the recording medium that is charged, by reducing a charge amount of the charged recording medium, wherein the charge eliminating apparatus is positioned at a stage that is after the relay apparatus and before the post-processing apparatus in a processing direction, and wherein the charge eliminating apparatus includes a non-contact charge eliminator that generates ions, and has a function of eliminating electric charge without coming into contact with the recording medium by supplying the recording medium with the ions generated by the non-contact charge eliminator. 2. The image forming system according to claim 1 , wherein the charge eliminating apparatus further includes a contact charge eliminator, and the non-contact charge eliminator is positioned downstream of the contact charge eliminator. 3. The image forming system according to claim 2 , wherein the contact charge eliminator is a charge eliminating roller. 4. The image forming system according to claim 1 , wherein the non-contact charge eliminator generates the ions by performing corona discharge.
