Abstract

The invention provides a toner carrying device and an image forming device. The toner carrying device includes a flexible sheet, and a sheet moving mechanism for allowing the flexible sheet to move back and forth by pulling the flexible sheet. In the flexible sheet, a toner passage hole for leaving a first opening section of a toner carrying pipe to open is provided. In a case where the toner passage hole is divided into first through three areas in such a manner that the first area is provided on a side of one end of the flexible sheet in a direction orthogonal to a moving direction of the flexible sheet; the second area is provided on a side of the other end of the flexible sheet in the direction orthogonal to the moving direction; and the third area is provided between the first area and the second area, the third area extends broader in the moving direction than respective of the first and second areas. This allows the flexible sheet partially having the toner passage hole in its area to move smoothly.

Description

technical field [0001] The present invention relates to a toner conveying device used when conveying toner to a predetermined position. Background technique [0002] Electrophotographic image forming apparatuses can form high-quality images in a short period of time with simple operations and are easy to maintain and manage. Therefore, they are widely used in, for example, copiers, printers, facsimile machines, and multifunction machines. An electrophotographic image forming device (hereinafter simply referred to as an "image forming device") includes, for example, a photoreceptor, a charging device, an exposure device, a developing device, a transfer device, and a fixing device. [0003] The photoreceptor is a roll-shaped member with a photosensitive film formed on the surface. The charging device receives voltage application and charges the surface of the photoreceptor to a predetermined potential. The exposure device irradiates light corresponding to image information t...
