り確実に防上する事が出来る。The present invention is not limited to the above-mentioned embodiments and can be modified in various ways. For example, the developer may be magnetic or non-magnetic as long as it is a powder, and the developing roller of the developing device may also be an insulated roller. It may be a type that electrostatically attaches the toner, but in a type where the developer is restrained by magnetic force as in the second embodiment, the developer is limited to a magnetic one. . Furthermore, the material or shape of the fixing member, the installation position, etc. are arbitrary; for example, the filling member OI in the embodiment is
A flexible sponge or the like may be used as long as it fills the inner space, or a flat magnet may be used at the tip of the filling part (28a) of the filling member, as shown in another modification in FIG. ) (28b) is attached to further magnetically restrain the powder developer ell), the degree of freedom thereof is further reduced. However, in this case, in order to prevent the powder developer (Iυ) from being magnetically attached to the magnet (18b) when taking out the filling member, a vinyl sheet (total) is placed between the filling member and the powder developer (11). It is necessary to provide a non-magnetic material such as.Furthermore, by gluing the developing section cover as in the example, it is possible to more reliably prevent powder developer from spilling from the opening in the container during transportation. I can do it.

Even if the developing device is transported as it is, the powder developer will not be moved due to vibrations, preventing deterioration of the powder developer during transportation, reducing spillage from the opening, and making it easier to install the main unit. In some cases, it is not necessary to inject powder developer into the developing device as in the past, which simplifies the installation process and prevents surrounding devices from being contaminated by developer scattering during injection. I can do it. Furthermore, as shown in the example, if the opening of the housing is covered with a developing section cover during transportation, leakage of powder developer from the opening during transportation can be completely prevented, and the overall By sealing the developing device with a cover, deterioration of the powder developer or the main body due to moisture can be prevented and long-term storage can be achieved.
