う手法かとられていた。[Prior Art] In conventional electrophotographic copying machines, developer is stored in a developer storage container, and transported and stored tightly sealed with a sheet-like sealing member to prevent contamination with foreign matter and deterioration due to humidity. Some devices supply developer from a developer storage container to a developing section by unsealing a sealing member after installing the device. However, since the developer is extremely fine powder particles, it may be unevenly stored in the L storage container during transportation and agglomerated into blocks due to vibration, so that it may not be uniformly supplied to the developing section when the seal member is opened. In preparation for such a case, a method has been used in which a developer storage container is positioned to the side of the developing section, and when the seal member is opened, the developer falls into the developing section and is crushed.

1, and the bottom plate of the developer storage container is set at an angle larger than the angle of repose of the developer. When the sealing member 52 is pulled out, the developer falls under its own weight, and the developing sleeve 53 is a developer carrier. It was then supplied to the developer for development.
［発明か解決しようとする課題］

上げる方式を採用せざるを得ない。[Problems to be Solved by the Invention] However, if there is a restriction in the positional relationship between the developing section and the developer storage container as in the above-mentioned conventional example, the configuration of the entire device may be affected. As shown in the figure, vc!
In a device that conveys a recording material from the bottom to the top of the device and develops it, the image forming mechanism is concentrated on the right side, making it possible to achieve downsizing and cost reduction, especially in printers. However, in such a configuration, it is impossible to position the developer storage container 50 above the developing section 51. Therefore, it is necessary to adopt a method in which a rotary agitation conveyance means is provided in the developer storage container to pump up the developer.

た。However, in the one-rotation stirring conveyance system,
When vibrations are applied during transportation, especially in the longitudinal direction (the direction perpendicular to the plane of the paper), the powder developer is biased to one side of the developer storage container in the above-mentioned direction and agglomerated. In this state, the torque required to rotate the above-mentioned agitation conveyance means is about 5 to IO times that in the normal state, and the agitation conveyance means is equipped with a motor that generates enough torque to overcome this load torque and a sufficiently strong agitation conveyance means. is required. Moreover, the agglomerated state of the developer mentioned above is rapidly resolved when the stirring conveyance means starts rotating.
Along with this, the load torque also decreases rapidly. For this reason, there are problems in that the entire apparatus requires the use of an inefficient high-torque motor and the need to excessively reinforce the stirring and conveying means.

。In order to solve the above problem, it is necessary to loosen the agglomerated developer in the developer storage container at the initial stage of operation after installation of the device.
47588, the rod-shaped member is always present in the developer storage container, so the rotary agitation conveyance means interferes with each other in the developer storage container during operation. There was a problem with that.

となく容易に回転を始める。Figure 2 shows how vibrations caused by transportation, etc. can cause damage to the equipment. If the device is not used in this state, as described above, the torque required by the gear 17 to rotate the developer agitation and conveyance means 4 is extremely large. At this time, the operator handles the handle 13 of the sheet member 10.
If the angle is subtracted, the sheet member 10 will be removed from the protrusion 11 and will change from a wavy shape to a straight shape. At this time, the surface of the sheet member IO serving as the stirring surface moves under surface pressure from the developer 12,
Since the developer 12 is scraped through, the developer 12 that has been aggregated
is crushed. As shown in 3rd t\1, the sheet member lO moves in a straight line while gradually coming out from the developer storage container 3, and the seal member i at the rear end, which is another stirring surface.
After loosening the developer 12 by transporting it to a certain extent from the side 5, the developer will not be stirred even if the process cartridge is installed in the main body of the device (not shown) and the device is started. Rotation starts easily without requiring excessive torque from the conveying means.

FIG. The developer stirring and conveying means 4 is placed in advance at a position where it will not interfere with the sheet member 10 during assembly. When the sheet member IO is pulled out, the lower side of the developer 12 is activated as shown in the figure, so that the developer 12 is prevented from dripping from above into the cavity formed on the lower side, and the crushing action is accelerated. As the sheet member 1◎ is continuously pulled out, the seal member 15 attached to the rear end of the sheet member 1G engages and is fixed with the locking portion 14 provided on the inner wall of the developer storage chamber s3, as shown in FIG. Ru. At this time, the seal member 15 and the locking portion 14 are engaged with each other by sandwiching the sealing material 16 such as urethane foam pasted on the locking portion 14, so that this portion is sufficiently sealed. Then, the seal body 15 is fixed and a perforation or notch is provided so that the sheet member 10 can be cut at the portion P when it cannot be removed any further. In this way, the unreliable sheet member IO can be easily cut and thrown away, and since the sealing body 15 is fixed to the engaging part 1E 14 on the inner wall of the developer storage chamber's3, the developing agent can be Interference with the agent stirring and conveying means 4 can be avoided. Moreover, the seal body 15 is
The developer storage container 3 is sufficiently sealed to prevent the developer 12 from leaking out of the developer storage container 3.
