PURPOSE: To simplify the structure of a toner recovering apparatus and improve the maintenance easiness and reliability by installing a pulling member which moves interlockingly with the movement of attachment of a toner recovering filter to a filter installation part and which joins the air sucking inlet of a toner recovering filter to an another end of a joint. CONSTITUTION: In the case a toner recovering filter 1 is taken off, a joint 6 is opened and a toner recovering filter 1 is pulled out along guiding members 11e, 4 to take the filter 1 off. In the case a new toner recovering filter is set, a toner recovering filter 1 is put on an exhaust part sealing member 5 and pushed while being slid along the guide members lie, 4. Being pushed further, the toner recovering filter 1 is brought into contact with a wire 9. Since no tension is applied to the wire 9 in the condition that a joint 6 is opened, the joint 6 is not pulled in the direction of the toner recovering filter 1 but as the toner recovering filter 1 is pushed further, tension is generated in the wire 9 and the joint 6 is pulled by the wire 9 and closed. |
