[0075] A detailed description will be given of a second embodiment of the present invention with reference to the accompanying drawings. Since this embodiment differs from the first embodiment mainly in changes in the structure of the stopper, the discussion will focus on the differences between the structural features of the stopper and those of the first embodiment. Components that are the same as those of the first embodiment are denoted by the same reference numerals, and repeated descriptions thereof will be omitted.

[0076] Such as Figure 9A and 9B As shown, the stopper 100 includes a stopper body 110 and a locking member 120 .

[0077]Such as Figure 9A As shown, the stopper body 110 is formed in the shape of a cylindrical tube having a bottom; closed. The stopper body 110 further includes a cylindrical tubular wall portion 117 disposed on and protruding from a bottom portion 116 inside the side wall portion 111 . At the bottom end of the tubular wall portion 11...

Abstract

A stopper for plugging a developer filling port includes a stopper main body and a lock member engageable with the stopper main body. The stopper main body is configured to be fitted to the filling port and shaped like a tube with a bottom. The lock member has a rigidity greater than that of the stopper main body, the lock member engaged with the stopper main body serves to restrict deformation of the stopper main body. A developing device for use in an image forming apparatus includes the stopper configured as described above to be fitted to its developer filling port.

Description

technical field [0001] Articles or devices consistent with one or more aspects of the present invention relate to a stopper adapted to a filling port for developer, and a developing device including the stopper. Background technique [0002] In view of environmental friendliness, the cartridge filled with the developer used in the laser printer may be collected after use, refilled with the developer and reused. [0003] A stopper fitted to the filling port of the cartridge is designed differently for refilling the developer. [0004] For example, a certain type of stopper is known in the art, having a thin-walled structure with a bottom provided with a knob, which is operable to pull out or push in, so that the user can adapt the stopper under high pressure. Deformation between the fitting state and the low pressure fitting state, thereby opening or closing the filling port smoothly (see JP 10-111596A). Another type of stopper with an engageable portion is also known in th...
