Abstract

PURPOSE:To simplify and speed up start-up operation by supplying a start agent and toner to a prescribed part of a development case only by loading a start agent cartridge in an open space. CONSTITUTION:This device is equipped with the open space for loading the start agent cartridge 9 in a development case 1, a coupling member 11d for coupling the start agent cartridge 9 with a toner cartridge 2 so as to separate the seal 11 of the toner cartridge from the toner cartridge 2 when the start agent cartridge 9 is loaded in the open space, and an unsealing member 8b which is projected into the open space 10 and breaks and unseals the seal 12 of the start agent cartridge 9 when the start agent cartridge 9 is loaded in the open space 10. Consequently, the start agent cartridge 9 is only loaded in the open space 10 and then a start agent S and toner T can be supplied nearly simultaneously, so they are supplied easily and speedily.
