Abstract: An image forming system includes an openable portion, an operating unit, a cable, an accommodating portion, a cable cover, a retaining portion, and an opening. When the cable cover is viewed along a vertical direction, an edge portion of the opening and an end portion of the cable are defined, specifically, the opening defines an edge portion of an edge of the opening on a side where the openable portion is positioned with respect to a left-right direction, and the cable defines an end portion of an outer peripheral surface of the cable retained by the retaining portion with respect to the left-right direction. With respect to the left-right direction, the edge portion is positioned further on a side opposite from the side where the openable portion is positioned than the end portion is.

Abstract: In an image forming apparatus that includes a collection container for collected toner, the collection container is not easily pushed back by a reaction force against a closing force of a shutter provided in a feeding portion for the collected toner. A spiral rib guides a contact rib to move the sealing shutter in a direction of opening a transfer opening against an urging force of a twisted coil spring in the process of connecting a collected toner box to a feeding pipe. A low reaction force area guides the contact rib after the spiral rib in the process of connecting the collected toner box to the feeding pipe. An inclination angle of the low reaction force area relative to the direction of connecting the collected toner box is less than an inclination angle of the spiral rib relative to the direction of connection of the collected toner box.

Abstract: To provide an image forming apparatus in which a collection container for collected toner is not easily pushed back by a reaction force against a closing force of said shutter provided in a feeding portion for the collected toner. A spiral rib 52b guides a contact rib 37e to move a sealing shutter 52 in a direction of opening a transfer opening 51a against an urging force of a twisted coil spring 53 in the process of connecting the collected toner box 30 to a feeding pipe. A low reaction force area 52c guides the contact rib 37e after the spiral rib 52b in the process of connecting the collected toner box 30 to the feeding pipe. An inclination angle of the low reaction force area 52c relative to the direction of connecting the collected toner box 30 is smaller than an inclination angle of the spiral rib 52b relative to the direction of connection of the collected toner box 30.
