Image forming apparatus and image forming method

Abstract

The present invention provides an imaging forming apparatus capable of inhibiting paper jam, or poor fixation or poor image quality caused by curling of transfer materials, when the transfer materials are transmitted. The image forming apparatus comprises a transfer belt for transfer images; a roller around which the transfer belt is wound; a secondary transfer roller for transfer images on the transfer materials via forming a transfer nip by the butting between a belt driving roller and a transfer belt; a transfer material transporting unit for vertically upwardly sucking the transfer material, and transporting the transfer material with the image vertically down; a guide part which vertically upwardly sucks the transfer material transported by the transfer material transporting unit; a fixing nip comprising a heating roller and a pressing roller and between the heating roller and the pressing roller; a fixing part for transporting the transfer material guided by the guide part and fixing the images; and an airflow generating part for generating the airflow for absorbing the transfer material in a vertical direction.

Description

technical field [0001] The present invention relates to the use of a liquid developer composed of toner and carrier to develop a latent image formed on a photoreceptor, and then transfer the resulting developer to a transfer material such as recording paper, and transfer An image forming apparatus and an image forming method in which the transfer material is conveyed, and the toner image on the medium transferred on the transfer material is melted and fixed to form an image. Background technique [0002] An image forming apparatus that forms a developed image and transfers it to a transfer material such as recording paper is generally equipped with various transfer material transport mechanisms for transporting the transfer material. As such a transfer material transfer mechanism, there is known a structure in which the transfer material is adsorbed on the transfer belt by the air suction force generated by the multi-suction ports, moves with the transfer belt in this state,...

AI Technical Summary

Problems solved by technology

In addition, if the transfer material is conveyed in this state, there may be a problem that the transfer material falls off the conveyor belt during conveyance, or the transfer material cannot be guided to a predetermined position of the fixing part.

That is to say, the image forming apparatus equipped with the existing paper conveying device has the following problems: the transfer material falls off during conveying, causing a paper jam; to image quality degradation
