PURPOSE:To replace a waste toner container efficiently by operating a slide member after the replacement of a cleaner unit is indicated and then resetting a waste toner fullness mode when the output of a waste toner fullness detecting element is ceased. CONSTITUTION:When upper and lower units A and B are released from being mounted and the upper unit B is opened in case of trouble such as a jam, the cleaner unit 3 slants, so the waste toner 34 in a waste toner container 31 is dislocated to contact the waste toner fullness detecting element 33. If this waste toner 34 does not return to its original state and is still dislocated, the waste toner fullness detection signal is outputted at this time. In this case, the slide member 36 returns the dislocated waste toner 34 to the horizontal state. When the output of the waste toner fullness detecting element 33 is ceased through said operation, the waste toner fullness mode is reset. |
