Abstract

PURPOSE:To prevent residual toner from leaking from an insertion opening by providing an air opening part on the inner side of a toner hopper in the insertion direction of a toner cartridge and communicating the air opening part with a developing tank. CONSTITUTION:The inserted cartridge 3 is rotated and a tape 15 is removed to make toner TN falls on a sponge roller 4 from a hole 151, and when the emptiness of a developing tank 2 is detected, the roller 4 rotates to put the toner TN in the tank 2. This toner TN is scooped up by a magnetic roller 6 while agitated by a paddle roller 5, and supplied for development from a development opening part 10. Here, when the compressed air 18 in the hopper when the cartridge 3 is inserted is discharged from the air opening part 7, its flow velocity is extremely fast, but the capacity of the tank 2 is sufficiently large and the opening part 10 extends lengthwise, so the speed of the air flowing in the tank 2 from the air opening part 9 of a ceiling wall 16 becomes slow, internal toner is not scattered, and there is no influence exerted in the tank 2.
