Tonerverpackung und Entwicklungsvorrichtung zur Verwendung in einem elektrofotografischen Gerät

摘要

A toner pack for use in an electrophotographic apparatus is formed of a polypropylene resin containing 30 to 50 wt% calcium carbonate filler. This resin has a high deformability, and generates a small amount of heat at the time of incineration thereof. Thus, the used toner pack can be disposed of together with flammable products made of paper and/or wood. Further, at the time of disposal, it is possible to fold the used toner pack to reduce its size.
