保たれた状態で駆動が伝達される。 Next, when the upper housing is closed in the direction of arrow B, the rotational center axis 5a of the photosensitive drum 5 fits into the groove of the positioning block 21a provided in the lower housing, and the drum gear 22 provided at the end of the photosensitive drum and the lower housing A drive gear 23 provided on the body makes contact. At this time, if the tips of the teeth of the drum gear 22 and the drive gear 23 touch each other and do not mesh normally, the process cartridge 4 is moved to the drive gear 23 as shown in FIG.
It is pushed upward by the drag force F A from the tip of tooth No. 3. At this time, the process cartridge 6 is pressed downward by a force F B by the spring member 20 provided in the upper housing. The drive gear 23 is driven in the direction of the arrow by a motor M provided in the lower housing via a gear train. When the drive gear 23 starts rotating, the drum gear 22 immediately meshes with the drive gear 23 because the force F B is applied thereto. Then, as shown in FIG. 4, if the angle θ between the center O 1 of the drum gear 22 and the center O 2 of the drive gear 23 with the vertical direction is larger than the meshing pressure angle α of the gears, the drum gear 22 will have a tooth surface. It receives a force F perpendicular to , and a force F1 in the vertical direction of this force F acts downward. Therefore, as shown in FIG. 5, the rotation center shaft 5a of the photosensitive drum 5 is pressed against and fitted into the groove of the positioning block 21a, and the drum gear 22 and the drive gear 23 are driven with the distance between their axes always kept constant. is transmitted.
