Title: Image forming device
Inventor: GOTO YOICHIRO
IPC: G03G9/083
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which is ozoneless and reduced in voltage and cost by using carriers obtained in such a manner that iron powder having strong saturation magnetization is turned into cores, as magnetic carriers and specifying the grain diameters of the carriers. SOLUTION: When a photoreceptor 12 is rotated and residual toner reaches the position of a developing device 16, the sticking force of the residual toner to the photoreceptor 12 is made weak, so that the residual toner is attracted by the magnetic carriers 18b, to be recovered to the developing device 16, as a result. At this time, as the magnetic carriers 18b, the carriers obtained by turning the iron powder having the strong saturation magnetization into the cores are used. The grain diameters of the carriers are set 30μm<=70μm. Thus, the generation of the following problems is prevented; the photoreceptor 12 is scratched by the carriers between a recording paper and the photoreceptor 12, because the carriers 18b are stuck to the photoreceptor 12, further, the thickness of a film is locally reduced by the scratch of the photoreceptor 12 and a pinhole is generated by an abnormal discharge from a contact electrifier, in a place where a withstanding voltage is decreased, so that a failure in electrification occurs in a pinhole part and a defect such as a horizontal streaky image occurs.

CONSTITUTION:When an outer lid 1 is strongly pressed in an initial lid-fitting condition in which a seal fitting part 22 of an inner lid 2 contacts the upper end of a container opening 3, the outer lid 1 lowers to reduce the diameter by a wedge action due to a taper surface 6a of a larger ring of groove 6 of an enlarged taper periphery 23 of the inner lid 2 and a smaller ring of groove 7 of the outer lid 1 and an enlarged tapered peripheral wall part 23 of the inner lid 2 are fitted by press. In this condition, said periphery 23 diameter is reduced to closely contact an outer surface of the container opening 3 by strong press to the inner diameter at the taper surface 7a of the smaller ring of groove 7. Accordingly, the container opening 3 can be completely sealed. And as a hook protrusion 25 is pressed to fix at a lid-fitting step 3a of the container opening by the wedge action of a taper face 7a, the outer lid can be capped so closely that it can not be separated without cutting off.
