Problems solved by technology

[0006] In addition, although it is possible to form a high-resistance layer by oxidizing the surface of the recovery roller, etc., the electrostatic adsorption force between the recovery roller and toner and paper powder is higher than the abutting force between the recovery roller and the sealing member, thereby Toner is prevented from being intercepted by the seal member and the side seal member. However, if the adsorption force between the recovery roller and the toner is strengthened, it will be difficult to scrape off the toner on the recovery roller by the cleaning blade. question
In addition, if the pressure applied by the cleaning blade to the recovery roller is increased in order to increase the force for scraping off the toner, there will be problems such as wear of the cleaning blade and an increase in torque applied to the recovery roller.

Embodiment Construction

[0016] Next, an image forming apparatus according to an embodiment of the present invention will be described with reference to the drawings.

[0017] First, refer to figure 1 A general configuration of the color printer 1 (image forming apparatus) will be described. figure 1 It is a schematic diagram roughly showing the configuration of a color printer according to an embodiment of the present invention. Also, in the instructions below, figure 1 The near side of the paper in the figure is the front side (front side) of the color printer 1 , and the left and right directions are based on the direction when the color printer 1 is viewed from the front.

[0018] The color printer 1 has a box-shaped printer main body 2 , and a paper feed unit 4 for supplying transfer paper from a paper feed cassette 3 is provided at a lower portion of the printer main body 2 . A paper output tray 5 is provided on the upper part of the printer main body 2 . Inside the printer main body 2 , a t...

Abstract

An image forming apparatus includes an image carrier, a rotating brush, a collecting roller, a cleaning blade, a sealing member and a side sealing member. The sealing member has an extension part extending outside from each end of the collecting roller in an axial direction. The sealing member comes into contact with the collecting roller between a contact area between the rotating brush and the collecting roller and the cleaning blade and then prevents backflow of the residue. The side sealing member lifts the extension part toward the collecting roller on an outside at a predetermined interval from a position corresponding to each side edge of a maximum-width sheet passing region on the image carrier.

Description

technical field [0001] The present invention relates to an image forming apparatus having a cleaning device for removing residual toner from an image carrier. Background technique [0002] In electrophotographic image forming apparatuses such as copiers, printers, facsimile machines, and all-in-one machines, after the toner image is transferred onto transfer paper, the toner remaining on the image carrier is removed by a cleaning device. In addition, in an image forming apparatus capable of forming a full-color image, a resin-made intermediate transfer belt or an intermediate transfer belt having an elastic layer is used as an image carrier. [0003] When an intermediate transfer belt made of resin is used as an image carrier, the following cleaning device is widely used due to its simple structure and low price: In this cleaning device, the edge portion of a cleaning blade made of urethane rubber or the like The surface of the ribbon is brought into pressure contact to scr...
