Embodiment Construction

[0017] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. The image forming apparatus 100 in FIG. 1 is shown as an example of a printer having an electrophotographic recording unit. However, it is not limited thereto, and the present invention may also be a copier having an image reading device, a facsimile device, or a so-called multifunction machine having these functions. In FIG. 1 , the main body 1 of an image forming apparatus 100 is a paper feed unit 2 for recording paper (paper), an image recording unit 3 for electrophotography, and a discharge unit 4 for printed recording paper arranged in a vertical direction. sequentially stacked. The paper feed unit 2 for recording paper includes a paper feed cassette 201 , a separation feed roller 202 , and a separation pad 203 . The paper feeding cassette 201 can store a plurality of sheets of recording paper, and can be inserted into and drawn out from the apparat...

Abstract

An image forming device (100) includes a process unit (50,80), a toner containing portion (12,15), and a trapping member (8,14). The toner containing portion (12,15) is arranged in relationship to the process unit (50,80) and connected to the process unit (50,80) so as to construct a toner transporting mechanism. The toner transporting mechanism includes a toner receiving / supplying portion (T1,T3) having a toner receiving port and a toner supplying port such that the toner receiving port and the toner supplying port can be disconnectably connected to each other. The trapping member (8,14) is attached to a surface of a portion adjacent to the toner receiving / supplying portion (T1,T3) and traps leaked toner.

Description

technical field [0001] The present invention relates to an image forming apparatus. This image forming apparatus includes an image forming processing unit including a developing device, and a toner storage unit arranged in association with the processing unit. The image forming processing unit is connected to the toner storage section to form a toner delivery system. [0002] This application claims the priority of Japanese Patent Application No. 2006-246741 filed on September 12, 2006, the entire contents of which are incorporated herein. Background technique [0003] Electrophotographic image forming apparatuses are often used in copiers, facsimile machines, printers, or so-called multifunction machines having these functions. As such an image forming apparatus, there is an image forming apparatus using a two-component (toner and carrier) type developer. The image forming apparatus includes an image forming process unit such as a developer unit or a photosensitive drum ...
