Abstract

PURPOSE:To reduce the dumping frequency of residual toner and to reduce the constitution of a toner recovering device by recovering the residual toner temporally stored in a toner receiving member of a cleaning device into a photosensitive drum. CONSTITUTION:The residual toner temporally stored in the toner receiving member of the cleaning device is recovered into a rotary room 23 having a large capacity which is formed by the photosensitive drum 2 through a carrier 29 or the like by a coil 30 which is a carrying member rotating by interlocking with the rotation of the drum 2. Consequently, the dumping frequency of the residual toner can be reduced, the formation of a toner recovering cotainer can be omitted and the constitution of the toner recovering device can be reduced.

In such a configuration, while the photosensitive drum (2) is rotating, the coil (G) is also rotated by being driven by the gear 0]).
The remaining toner that has fallen into the toner receiver (1) is transferred to the photosensitive drum (2) via the conveyance path (2) and the passage (3) by the coil (3).
) is transported to the toner collection chamber (2) from the center of the end. The photosensitive drum (2) is charged in one rotation, irradiated with light beam (4a),
Since development, transfer, irradiation with light from the lamp α1, cleaning, etc. are carried out, the outer diameter is large, and therefore the inside is also large. Since unnecessary toner is collected in this wide dead space, toner disposal work can be significantly reduced.
When the interior is filled with toner, the photosensitive layer of the photosensitive drum (2) may also deteriorate, and there may be no need to take out and dispose of the toner inside the photosensitive drum (2). Also,
Since there is no need to separately collect the remaining toner in a separate container, the apparatus can be made smaller.
