Image forming apparatus provided with recovery container for waste toner

An image forming apparatus comprising:

• an image forming unit that forms an image on a sheet,
• a sheet conveying unit configured to convey a sheet along a conveying path extending in a substantially horizontal direction vertically below the image forming unit,
• a recovery container that is provided between the image forming unit and a door of the image forming apparatus and above the conveying path, and that stores waste toner discharged from the image forming unit, the recovery container removable from the image forming apparatus via the door, and
• one or more cleaning devices disposed at one or more elements of the image forming unit,
• one or more waste toner conveying pipes that convey the waste toner discharged from the image forming unit to the recovery container;
• the one or more waste toner conveying pipes include:
• a first waste toner conveying pipe extending from a first cleaning device of the one or more cleaning devices toward the recovery container in a direction toward the door;
• and
• a second waste toner conveying pipe extending from a second cleaning device of the one or more cleaning devices toward the recovery container in a direction toward the door,
• the recovery container comprises
• a casing including an accommodating unit for storing waste toner, and
• first and second conveying units for conveying the waste toner in the casing, the casing comprises
• a first receiving port for receiving the waste toner conveyed by the first waste toner conveying pipe, and
• a second receiving port provided below the first receiving port, for receiving the waste toner conveyed by the second waste toner conveying pipe, wherein the image forming apparatus further comprises
• a detection unit for detecting waste toner contained in the casing, at a detection position above the first conveying unit,
• wherein
• the first conveying unit equalizes height of upper surface of the waste toner accommodated in the accommodating unit,
• the second conveying unit conveys the waste toner received from the second receiving port to a position above the detection position,
• the second conveying unit further includes a transmission unit that transmits rotational force to the blade portion of the second conveying unit, at an upstream end portion in the conveying direction of a rotary shaft of the second conveying unit,
• the second conveying unit is positioned in a skewed position relative to the first conveying unit, and
• wherein each of the first conveying unit and the second conveying unit extends linearly from a first end of the respective conveying unit to a second end of the respective conveying unit opposite to the first end.
