<P>PROBLEM TO BE SOLVED: To provide a developing kit that invalidates improper refilling of toner or preventing it after toner in the inside is consumed, the amount of residual toner becomes zero and the life of the developing kit ends. <P>SOLUTION: When a sealing cap 100 constituted of a cap part 101 and a member to be supported 102 is pushed into a toner filling port 73-1, the greatly spread flexible pawl 108 of the member 102 is bent inward and advances while sliding on the inner wall of the port 73-1 and pierces through the port 73-1. When the cap part 101 is perfectly engaged with the port 73-1, the member 102 is stably supported by the cap part 101, and the pawl 108 is restored to an original shape that it is widened toward the end and its tip faces the inner wall surface of a toner container near the port 73-1. By forcibly detaching the cap part 101 from the port 73-1 as shown by an alternate long and two short dashes line, the member 102 is disengaged from the cap part 101 as shown by the alternate long and two short dashes line, and drops downward to hinder the working of the developing kit. <P>COPYRIGHT: (C)2004,JPO |
