Image forming apparatus

An image forming apparatus comprising:

• an image holding body;
• a developing device that causes a developer to adhere to the image holding body;
• and
• a supply device that supplies the developer to the developing device and that includes an intersection direction flow path, which is a flow path that extends in an intersection direction and through which the developer passes, and a downward flow path, which is a flow path through which the developer moving through the intersection direction flow path passes and that extends downward so that the developer moving downward passes through the downward flow path, the intersection direction being a direction intersecting a perpendicular direction,
• wherein an upper end portion of the downward flow path is provided with an opening that faces an upper side and that the developer moving through the intersection direction flow path enters, and
• a guide portion that causes the developer moving through the intersection direction flow path to move downward is provided at a faced position that the opening faces.

An image forming apparatus comprising:

• an image holding body;
• a developing device that causes a developer to adhere to the image holding body;
• and
• a supply device that supplies the developer to the developing device and that includes a downward flow path that includes an opening facing an upper side, that extends downward from the opening, and through which the developer moving downward from the opening passes and a transport member that extends in a direction intersecting a perpendicular direction and that transports the developer toward a faced position that the opening faces from a position separated from the faced position,
• wherein the transport member includes a rotary shaft that extends along a transport direction of the developer and push-out portions that are supported by the rotary shaft and that push out the developer toward an opening side, and
• at least a portion of a facing portion, which is a portion of the transport member that is positioned at the faced position that the opening faces, is not provided with the push-out portions, outer diameters of the push-out portions provided at the facing portion are smaller than outer diameters of the push-out portions positioned at the position separated from the faced position, or an arrangement pitch of the push-out portions provided at the facing portion is smaller than an arrangement pitch of the push-out portions positioned at the position separated from the faced position.
