An image forming system.

In general, a wet electrophotographic printing machine forms an electrostatic latent image by scanning a laser beam through a laser scanning unit on a photosensitive medium, and then sprays a developer (hereinafter referred to as an “ink”) between the photosensitive medium and the developing roller to form a photosensitive medium. It develops and transfers it onto printing paper.

In order to form an image corresponding to the electrostatic latent image on the photosensitive medium, a developing unit corresponding to the colors of yellow, magenta, cyan and black is provided. Such a developing unit delivers a developing container for supplying ink to a developing roller while maintaining a predetermined level of ink, an ink supply unit for supplying ink to the developing container, and ink for filling the developing container onto a photosensitive member.

It consists of a cleaning roller that cleans the afterimage and mixes the ink in the developing container during normal operation.

In order to enable continuous printing by the circulation of the photoconductor, such a developing device is a medium for responding to the image to be implemented and developing material coated on the photoconductor by the developing apparatus to relay the image transfer to the recording paper or recording paper during the transfer process. 100% transition to the furnace should be made.

However, 100% transfer of the developing material to the recording paper or the medium during the transfer process is practically difficult and a small amount of the developing material remains in the photoreceptor although there is a difference in degree after the transfer process.

Residual developer that cannot be removed is accumulated in proportion to subsequent prints, resulting in poor print quality. In order to solve such a problem, conventionally, a cleaning rod was contacted with a photosensitive member to remove residual developer. In addition, the removed residual developer is collected in a collection container and then transferred to a waste ink tank for disposal.

However, in the related art, since the waste ink transferred to the waste ink tank is in a liquid state, there is a possibility of leakage during the parts replacement process, and thus there is a difficulty in handling that requires very careful handling such as maintaining a horizontal or constant posture.

As shown in FIG. 1, the image developing apparatus includes a developing unit 10, a waste ink tank 30, and a solid material input unit 50.

The developing unit 10 is a portion for processing a predetermined image on the printing paper 1. Specifically, as shown in FIG. 2, the developing container 12 allows ink to be supplied to the developing roller 11 while maintaining a predetermined level of ink, and the ink filling the developing container 12 is used as a photosensitive member. (13) the developing roller 11 which serves to transfer the image, the developing roller 11 which adheres the developing roller 11 to a predetermined amount of ink, and an excessive amount of ink to filter out a constant amount of ink at all times. It consists of a metering blade (16) to reach the photosensitive member (13) and a cleaning roller (17) which is made of a sponge while cleaning the afterimage on the outer peripheral surface of the developing roller (11) to mix ink in the developing container during normal operation. .

On the other hand, the cleaning blade 18 for cleaning the residual developer that is not removed in the photosensitive member 13 after the transfer process of the photosensitive member 13, and the collection container 19 for collecting the removed residual developer is composed.

The waste ink tank 30 accommodates the waste ink collected in the collection container 19, and a waste ink supply line 31 connected to the collection container 19 is provided at one side.

Solid material input unit 50 is installed on the upper side of the waste ink tank 30, as shown in Figures 2, 3, 4 and the solid material input base 51 having an opening 51a through which the lower part is penetrated. Is installed in the solid material input base 51, the solid material separating storage 53 for partitioning and storing a predetermined amount of solid material 52, and the solid material separating storage 53 to rotate in a predetermined direction It consists of a drive motor 55.

As the solid material 52, a material having excellent hygroscopicity, for example, it is preferable to use that which absorbs and solidifies an organic solvent corresponding to a predetermined multiple of its own volume.

Solid material separation storage 53 is a plate-shaped wing (53a) is disposed in a radial shape while maintaining a predetermined angle around the axis 56 of the drive motor (55).

On the other hand, at one end of the solid material input base 51 is stored in the solid material separating storage body 53 inside the solid material input base 51 and in a state in which a predetermined amount of solid material 52 is stored in each compartment space. A cap 57 is further configured to cover one end of the solid material input base 51.

The partitioning of the solid material separating and storage body 53 is part of quantifying the amount of solid material for solidifying the waste ink generated after processing the predetermined number of sheets of the developing unit 10. At this time, one place of the partition space shown in FIG. 4 is left as an empty space. This takes into account that the opening 51a is formed in the lower part of the solid material injection base 51.
