の一部破断の側面。Although there are development methods, the present invention is particularly applicable to supplying toner for dry development. In the dry development method, there is also a one-component developer called a two-component developer, which is a mixture of a carrier made of magnetic powder, etc., a mixture with a toner, and a toner that already contains magnetic powder. In the case of a one-component developer, the developer itself is used to supply toner, and in the case of a two-component developer, the toner is supplied. The description of the invention will specifically refer to the case of toggle feeding. In electronic copying machines and the like that use two-component developers, an electrostatic latent image is formed on the photosensitive layer by a known process in conjunction with an optical system and an electrical system, and the image is developed in a developing section. . In the case of development, toner, which is powder made of resin, is mixed with magnetic powder called a carrier at a concentration of several percent by weight to form a developer. The toner is electrostatically attracted to the magnetic powder, and An aggregate of magnetic powder as a core is subjected to development. When an electrostatic latent image of a different polarity than the toner formed on the photosensitive layer rubs against the developer, the toner is attracted to the electrostatic latent image by electrostatic force, and the toner is separated from the magnetic powder. , only the magnetic powder remains in the developing device, and the toner is transported out of the developing device as a toner image to the next step, a transfer section. Therefore,
Since the toner in the developing device is consumed, the concentration of the developer decreases, making it impossible to obtain a good quality toner image. Therefore, an automatic developer detection device is installed in the developing device to detect the decrease in density due to toner consumption, and automatically transfer the toner stored in the hopper into the developing device via the control circuit and drive system. It replenishes the amount of developer in the developing device and keeps the amount of developer in the developing device constant. Depending on the above-mentioned toner supply,
When the toner in the hopper is empty and the toner in the hopper is refilled from the toner bottle, the toner becomes atomized and scatters, staining the hands and surrounding area of the operator. Although various inventions and ideas have been made and put into practical use in order to prevent stains, their effects are insufficient. The present invention has been made in view of this, and although it is possible to use a toner bottle as a hopper, this description will specifically describe the case where toner is supplied from a bottle to a hopper. FIG. 1 is a partially cutaway side view of an embodiment including the essential parts of the present invention.

。It is a diagram. The photosensitive drum 1 on which the photosensitive layer 3 is formed on the surface of the conductive drum 20 is rotated in the direction of the arrow. Around the photosensitive drum 1, there is a known device that controls the operations of charging, exposure, development, transfer, and toner removal. The developing unit w4 has a magnetic roller 7 internally fixed in the case 5, which is made of a non-magnetic material, rotates in the direction of the arrow, and is detached from the sleeve 6 and is magnetically applied to a predetermined position. The developer 8 is collected and adsorbed onto the sleeve 6 by the magnetic force of the magnetic roller 7, and the developer is regulated by the protrusion 5 and the rock 9 as the IJ-Pro rotates, and the hair is styled using the magnetic brush 10. Form. As shown in the figure, the magnetic brush 10 rubs against the photosensitive layer 3, and the toner is attracted onto the static cage 1, and the toner is developed. After the magnetic brush 10 has rubbed against the photosensitive layer 3, the developer 8 is scraped off from the sleeve 6 by a scraping member 11 and conveyed onto the stirring section 13. The scraped off developer 8 is removed by the scraping member 11.
An electrical signal is generated when the developer is placed on top. The stirring part 13 is formed as a liquid roller, and a plurality of discs 15 are connected and fixed to a shaft 14, and a part K near the outer periphery of the disc 15 communicates with a group of lots 16 and imparts rotation in the direction of the arrow 1. 'The part where the density decreases during development or the newly replenished toner is sufficiently stirred. The toner hopper 17 has a valley at the bottom 18, and the toner supply port 19 is closed with a sponge roller 20, and by timely applying rotation in the direction of the arrow to the roller, a predetermined amount of toner 21 is replenished onto the stirring section 13. It is. That is, in response to the above-mentioned electric signal, the sponge roller 20 is given a predetermined tube rotation using an electric circuit and a motor (not shown), the toner 21 is replenished, and the density detection device 1
A predetermined amount of toner is supplied in consideration of the time delay from toner replenishment to detection until the signal generated from No. 2 disappears. Since the toner is replenished as described above after husking, the toner 21 in the hopper 17 is consumed, and the hopper 17 is busy replenishing the toner. Conventionally, there are many examples of automatic methods for replenishing toner in hoppers.
