PROBLEM TO BE SOLVED: To prevent deformation of a toner container and damage of the toner sealing by restraining the inside pressure in the toner container from becoming high by physical distribution, environments or the like, even in the toner container provided with high air-tight property. SOLUTION: This toner container 11A, consisting of the toner container main bodies 11a and 11b, and the toner sealing 50 for sealing an opening part 11i of the container main body, is allowed to feed the toner T to a developing roller 9c. In this case, a vent port 23 located on the toner packing port side of the container main body, is provided on a section apart from stored toner T in the toner container 11A at the toner packing time and at the time of a developing state, and a filter member is fixed so as to seal the vent port. Since the vent port is located in this position, possibility of clogging the filter member for sealing the vent port by the toner is extremely lowered, therefore the effect of the filter is satisfactorily demonstrated. |
