タンク２７内の液面はオーバフロー管２９により常に一
定の高さに保たれるようになっている。Conventionally, a developer solution is supplied to the developing head 14 by a developer supply device as shown in FIG. That is, the developer liquid is pumped up from the first developer tank 24 by the pump 25 via the conduit 26 to the second developer tank 27 located above, and the developer liquid is pumped up from the first developer tank 24 to the second developer tank 27 located below the second developer tank 27. 14 through a developer supply pipe 15 to the second
It supplies the developer liquid from the developer tank 27,
The developer liquid discharged from the developing head 14 is returned to the first developer tank 24 via the developer discharge pipe 16. The feeding control of the developer liquid to the developing head 14 is now in step 3! Opening/closing valve 28 provided in the liquid supply pipe 15
At the same time, the liquid level in the second developer tank 27 is always maintained at a constant level by an overflow pipe 29.

る上で大変都合の良いものである。Since such a developer supply device uses potential energy to feed the developer solution to the developing head 14, it is possible to keep the developer solution applied to the photosensitive surface 2a constant at all times compared to a system that uses a pump to forcefully feed the developer solution. The amount and flow rate can be controlled to be constant, and when the on-off valve 28 is closed, the on-off valve 2 in the developer supply pipe 15 can be controlled.
Since the developer liquid is retained in the downstream part of the valve 28, the developer liquid can be quickly supplied to the photosensitive surface 2a by opening the on-off valve 28, which makes it very difficult to control and manage the development state. It's convenient.

17'&L supply control, developer supply pipe 1
5 has a relatively small diameter. Therefore, if the on-off valve 28 is left closed for a long period of time, the toner will settle in the developer supply pipe 15 because the developer will remain in the developer supply pipe 15 and there will be no convection. A situation has arisen where this happens. - Furthermore, if the toner is left in the first developer tank 24 and the second developer tank 27 for a long period of time, the toner will settle in the same way as in the pipes. As a result of examining the shape of developer storage containers such as piping and tanks, it was found that toner sedimentation is more pronounced in containers that are longer than the pipe diameter and whose upper end is closed with a valve or the like. If the developing process is performed with the toner sedimented and in good condition, the toner concentration in the developer solution supplied to the photosensitive surface 2a is non-uniform, which rarely causes uneven development. .

It is an object of the present invention to provide a developer storage container for an electrophotographic apparatus that generates convection of the developer in the developer storage container so as to realize development in a good state even after the development is performed.

An electric heater 30 connected to a power source (not shown) is installed at the lower end of the body. Therefore, when the developer liquid remaining in the developer supply pipe 15 is heated appropriately by the electric heater 30, the lower part of the developer liquid in the developer supply pipe 15 becomes hotter than the upper part, and this temperature difference causes Convection occurs in the developer solution. That is, when the electrophotographic apparatus is left unused for a long time, the electric heater 30 is used to heat the developing solution during the unused period or shortly before use, thereby causing convection in the developer solution reservoir. The toner inside can be stirred to make the toner concentration uniform, and good, even development can be achieved.

As a temperature difference generating means, a block member 31 having a large heat capacity and a relatively low thermal conductivity is attached to the lower end of the string portion below the opening/closing valve 28 of the developer supply pipe 15 extending from above to the developing head 14. This is what I did. In general, the heat capacity of a member is C1, the thermal conductivity is T, and the internal temperature of a member is T
, the external environment temperature is T. Then, the speed of temperature change of this member is expressed as dT = 'i ('p-To) dt
c be done. That is, the block member 31 has poor followability with respect to changes in the external environmental temperature, and as shown in FIG. 1(c), a temperature difference is likely to occur between the external environmental temperature and the internal temperature of the block member 31. Therefore, in the downstream part from the on-off valve 28,
A temperature difference occurs between the lower part of the developer supply pipe 15 covered by the block member 31 and the upper part of the developer supply pipe 15 sensitive to external environmental temperature due to changes in the external environmental temperature, and due to convection of the developer liquid. The toner is stirred and the toner concentration becomes uniform, achieving good development. In this way, suitable materials for the block member that achieve natural toner agitation due to changes in external environmental temperature include water with a high specific gravity, metals and ceramics with a large weight, and materials that have a melting point within the natural change in external environmental temperature. A material with a large heat capacity such as a mixture of mirabilite and urea (melting temperature, 18°C to 22°C) can be considered. Possible options include covering with lfT thermal material.

れば良い。In each of the above-mentioned embodiments, the present invention is applied to a portion downstream of the on-off valve 28 of the developer supply pipe 15, which has a small diameter because the on-off valve 28 performs feeding control, and natural convection of the developer liquid is difficult to occur. As a matter of course, the present invention may be applied to a portion upstream of the on-off valve 28 to make the toner concentration uniform. It goes without saying that the present invention is not limited to piping, and may be used in tanks for storing developer. Further, the temperature difference generating means of the present invention may be one that cools the developer in addition to one that heats the developer. In this case, a cooling device or cooling fins are attached to the upper part of the developer supply pipe 15 to perform the development. It is sufficient to generate convection of the liquid.
