[0026] First, use figure 1 The overall configuration of the color printer 1 as an image forming apparatus will be described. figure 1 It is a schematic diagram showing the outline of the configuration of the color printer according to the first embodiment of the present invention.

[0027] The color printer 1 includes a box-shaped printer body 2 . A paper feed cassette 3 for accommodating transfer paper (not shown) is provided at the lower part of the printer main body 2 , and a paper discharge tray 4 is provided at the upper end of the printer main body 2 .

[0028] On the upper part of the printer main body 2, an intermediate transfer belt 5 serving as an image carrier is stretched between a plurality of rollers, and an exposure unit 10 constituted by a laser scanning unit (LSU) is disposed below the intermediate transfer belt 5, and A plurality of image forming sections 6 are provided along the lower portion of the intermediate transfer belt 5 . Each image forming sectio...

[0087] Next, use Figure 12 A second embodiment of the present invention will be described. Figure 12 It is a block diagram showing the configuration of the color printer according to the second embodiment of the present invention.

[0088] In the first embodiment described above, the rotation detection unit 57 including the pulse plate 73 and the sensor 74 is used as the detection unit, but in this embodiment, as Figure 12 As shown, an overcurrent detection circuit 83 is used as the detection unit. The overcurrent detection circuit 83 is connected to the drive motor 55 and the CPU 79, and is configured so that when the current flowing through the drive motor 55 (hereinafter referred to as "drive current") exceeds a threshold value (for example, 0.3A or 0.9A) (or greater than When it is equal to the threshold value), an overcurrent detection signal is sent to the CPU79. The overcurrent detection circuit 83 is constituted by, for example, a conventionally known circuit inc...

Abstract

The present invention provides a toner conveying device and its control method, a toner container, and an image forming device. The toner conveying device includes a toner containing container and a drive unit. The toner storage container has a container main body and a stirring portion. The drive unit has a drive unit, a detection unit, and a control unit. The control section judges whether the toner container is in an overloaded state based on the reception status of the detection signal from the detection section. Retry control. According to the present invention, when the toner cartridge is in an overloaded state, it is possible to melt the toner that has solidified on the device side and to perform toner replenishment normally.

Description

technical field [0001] The present invention relates to a toner conveying device for supplying toner to a developing device, a toner container containing toner, an image forming apparatus including these toner conveying devices and a toner container, and the toner A method of controlling an agent delivery device. Background technique [0002] Conventionally, in an electrophotographic image forming apparatus, a developing process is performed by supplying toner from a developing device to an electrostatic latent image formed on a surface of a photosensitive drum or the like. In addition, the toner used for such a development process is supplied from the toner storage container to the developing device by the conveying part while being stirred by the stirring part. [0003] In an image forming apparatus having such a configuration, the toner container may be overloaded immediately after the toner container is replaced or after an image forming operation has not been performed...
