Problems solved by technology

[0006] However, when the radius of curvature of the arc-shaped guide portion is set small, the paper conveyed from the linear conveyance path collides with the bent guide portion, making a collision sound, and at the same time, the corners of the paper are folded, which is easy paper jam etc.
In addition, coating organic paint on metal U-shaped guides also involves an increase in cost.
Moreover, when forming a color image, especially when forming a double-sided image, the amount of toner in the single-sided printing is large, so after the fixing of the single-sided printing, the hardness of the paper tends to increase. Reduced conveying performance of the guide

Abstract

A sheet transport mechanism is disclosed that has a simple structure and does not occupy a large amount of space. A return transport path includes a transport guide plate that guides and transports a sheet, a first U-shaped transport guide member having a curvature radius of approximately 60 mm or less, and a pair of transport rollers. The sheet conveying direction on the return transport path is changed by the first transport member, and the sheet is guided to a pair of sheet stopper rollers. Furthermore, a convex member is formed on the transport guide plate between the pair of transport rollers and the first U-shaped transport guide member in order to curve the sheet transported on the return transport path.

Description

technical field [0001] The invention relates to a paper conveying mechanism, in particular to a paper conveying mechanism in a paper conveying path of an image forming device. Background technique [0002] In an electrophotographic image forming apparatus, a charging device, an exposure device, a developing device, a transfer device, a cleaning device, and the like are provided around a photosensitive drum as an image carrier. Furthermore, a fixing device is provided on the downstream side of the transfer medium from the photosensitive drum. In such an image forming apparatus, first, the surface of the photosensitive drum is uniformly charged by the charging device. Then, according to the image information, the photosensitive drum is exposed to light by an exposure device to form an electrostatic latent image on the surface of the photosensitive drum. This electrostatic latent image is developed by a developing device. Here, in the case of a full-color image forming appar...
