A releasing mechanism usable for a toner supply container includes a rotatable structure, a stationary structure engaged with the rotatable structure, and a pump movably connected to the stationary structure. The rotatable structure has a first magnetic member. The stationary structure has an opening for releasing toner and a second magnetic member. The pump has a pumping portion that is expandable. A first force drives the rotatable structure to rotate relative to the stationary structure, such that the first magnetic member is alternatively aligned and misaligned with the second magnetic member. When the first and second magnetic members are aligned, the pump is pushed away from the stationary structure by a repelling force generated between the first magnetic member and the second magnetic member. When the first and second magnetic members are misaligned, the pump is pushed by a second force toward the stationary structure. |

1. A toner supply container for supply toner to an apparatus, comprising:
a container body having a first end and an opposite, second end defining an inner space therebetween for accommodating the toner; a releasing mechanism, comprising:
a gear having a first end and an opposite, second end that is fixed to the first end of the container body;a first magnetic member fixed to the gear;a releasing member having a first end and an opposite, second end, an opening in fluid communication with the inner space of the container body, and a sliding sheet slidable to cover or to expose the opening, wherein the first end of the gear is rotatably fixed to the second end of the releasing member;a pump movably connected to the first end of the releasing member;a second magnetic member fixed to the pump;an elastic member urging against the pump;a housing configured to accommodate a part of the gear, the first magnetic member, the releasing member, the second magnetic member, the pump, and the elastic member; anda first fixing member for fixing the second magnetic member, and a second fixing member for fixing the elastic member, wherein the pump has a first end in a plate shape, the first fixing member is disposed at one side of the first end of the pump, the second fixing member is disposed at the other side of the first end, and a protrusion hook of the second fixing member passes through a through hole of the pump and a through hole of the first fixing member, and fixes the first fixing member, the pump and the second fixing member together, wherein when a driving force from the apparatus drives the gear to rotate, the rotation of the gear causes the first magnetic member to rotate so that the first magnetic member is alternatively aligned and misaligned with the second magnetic member, when the first magnetic member and the second magnetic member are aligned at an aligned position, the pump is pushed away from the releasing member by a repelling force generated between the first magnetic member and the second magnetic member, or pulled toward the releasing member by an attracting force generated between the first magnetic member and the second magnetic member, and when the first magnetic member and the second magnetic member are misaligned at a misaligned position, the pump is pushed toward the releasing member by the elastic member, or pulled away from the releasing member by the elastic member. |
