摘要

PROBLEM TO BE SOLVED: To facilitate disassembling of a developing device at a recycling time. SOLUTION: A heat conductive member is caused to intervene in a space of a fused coupling faces formed between a developing frame 15 and a toner vessel 12 with its end portions 18a protruded. The heat conductive member fuses the coupling face when the end portions 18a are heated by a heating device 20 so that the developing frame 15 and the toner vessel 12 become separable. Instead of the heat conductive member, an energizing heating member is energizing heated. Or, a bimetal is heated so as to separate the coupling face.
