RECYCLING BOTTLE FOR TONER/DEVELOPER

PROBLEM TO BE SOLVED: To meet UL94-HB, fire-retardant specification, and to enable the incorporation and use of the bottle in an image forming device by formulating PCR (post consumer resin), and giving a thickness having a specific value or more. SOLUTION: The recycling bottle is produced formulating the PCR and, further, by giving a thickness of 0.5mm or more. It can be passed through a specific standard not by formulating the PCR into a virgin material but by forming the toner/developer bottle out of only the PCR and giving it the thickness of 0.5mm or more. It is preferable that PCR (HDPE) made by ENVIROTHENE be used as a recycled material and HDPE made by PAXON be used as the virgin material. By formulating the PCR, melt flow rate, flexural strength, elastic modulus in flexure, Rockwell hardness, heat deformation temperature, and specific gravity are made high. Even when the physical-properties values change in such a way, it can satisfies UL compatibility being the standard of fire retardancl required when the bottle used by being incorporated in the device.
