Image forming apparatus

An image forming apparatus comprising:

• a main body housing having an opening;
• a cover movable between an opening position at which the opening is opened and a closing position at which the opening is closed;
• a drawer movable in a first direction through the opening between an inner position at which the drawer is located inside the main body housing and an outer position at which the drawer is located outside the main body housing;
• a drum cartridge attachable to and detachable from the drawer, the drum cartridge including a photosensitive drum and a drum cleaner for removing waste toner from a peripheral surface of the photosensitive drum;
• a waste toner container for accommodating waste toner removed from the peripheral surface of the photosensitive drum by the drum cleaner;
• and
• a waste toner conveying tube for conveying the waste toner,
• wherein, when the drum cartridge is attached to the drawer and the drawer is at the inner position, the waste toner is conveyed from the drum cartridge to the waste toner container through the waste toner conveying tube,
• wherein, when the drum cartridge is attached to the drawer and the drawer is at the inner position, the waste toner conveying tube is movable in a second direction intersecting with the first direction between a first connection position at which the waste toner conveying tube is connected to the drum cartridge and a first disconnection position at which the waste toner conveying tube and the drum cartridge are disconnected,
• wherein, when the drum cartridge is attached to the drawer and the waste toner conveying tube is at the first disconnection position, the drawer is movable from the inner position to the outer position,
• wherein, when the drum cartridge is attached to the drawer, the drawer is at the inner position, and the waste toner conveying tube is at the first connection position, the drawer is not movable from the inner position to the outer position, and
• wherein when the cover moves from the closing position toward the opening position, the waste toner conveying tube moves from the first connection position toward the first disconnection position in conjunction with the movement of the cover.
