PURPOSE:To obviate such a convenience as immoderate force is applied on a seal sheet and it is broken, by piercing plural openings along the edge part of a toner replenishing port, in a sticking part to the toner replenishing port of the seal sheet. CONSTITUTION:In a sticking part of two lines in the longitudinal direction to a toner replenishing port 2 of a seal sheet 3, and its extended part, many openings 5 are pierced in a straight line, respectively. Accordingly, when the seal sheet 3 is peeled off, a part where the opening 5 is formed, and a part where the opening is not formed are peeled off successively. That is, the part where the opening 5 is formed can be peeled off by comparatively small force, since a sticking area is small, and by drawing the seal sheet 3 by small force on an average by its portion, the seal sheet 3 can be peeled off smoothly without being broken. Also, when the part where the opening 5 is formed and the part where the opening is not formed are peeled off alternately, the force required for peeling off the seal sheet 3 is fluctuated successively, and it gives a minute vibration to a hollow container 1. In such a way, a residual toner adhered to the inside of the hollow container 1 is shaken off into a toner hopper 6 and can be supplied. |
