Developer delivering device and image forming apparatus

An image forming apparatus comprising:

• an image holding member on which a latent image is formed;
• a developing unit that develops the latent image on a surface of the image holding member into a visible image;
• a transferring part that transfers the visible image on the surface of the image holding member onto a medium;
• a cleaning device that collects and cleans away a residue remaining on the surface of the image holding member to which the visible image is transferred;
• and
• a developer delivering device that delivers a developer collected by the cleaning device, the developer delivering device including
• a first delivering path through which the developer is delivered,
• a second delivering path through which the developer is delivered, the second delivering path being disposed on a downstream of the first delivering path,
• a helical delivering blade that is disposed in the second delivering path and delivers the developer by a rotation, and
• a developer breaking member that is disposed in a connecting portion of the first delivering path and the second delivering path and includes a breaking portion that is disposed opposite to a side wall of the second delivering path in a developer delivering direction of the second delivering path, a contact portion that is in contact with the helical delivering blade and extended in the developer delivering direction between the breaking portion and a center of the rotation of the helical delivering blade, and a coupling portion, the breaking portion having a first breaking portion disposed opposite to one of the side walls of the second delivering path, and a second breaking portion disposed opposite to the other side wall of the second delivering path, the contact portion having a first contact portion extended in the developer delivering direction between the first breaking portion and the center of the rotation of the delivering blade, and a second contact portion extended in the developer delivering direction between the second breaking portion and the center of the rotation of the delivering blade, the coupling portion coupling the first contact portion to the second contact portion.
