摘要： An electrophotographic image forming apparatus for forming an image on a recording material includes an electrophotographic photosensitive drum, a charging device for charging the photosensitive drum, a developing device for developing a latent image formed on the photosensitive drum into a toner image, a transfer device for transferring the toner image onto the recording material, a fixing device for fixing the toner image on the recording material, a motor, and a main assembly side gear for receiving driving force from the motor. A recess is formed substantially at a center of the gear, the recess having a polygonal cross-section, and a projection is provided at a longitudinal end of the photosensitive drum, wherein when the main assembly side gear rotates with the recess and projection engaged with each other, rotational driving force is transmitted from the gear to the photosensitive drum through the recess and the projection with the projection being pulled into the recess, wherein a free end of the projection and a bottom surface of the recess are contacted to each other so that the process cartridge is positioned in place in a longitudinal direction of the photosensitive drum relative to the main assembly. A moving device imparts relative movement between the recess and the projection in a longitudinal direction of the photosensitive drum to engage the projection with the recess.

摘要： There is provided a digital controller which can reduce a variation in output voltage as compared to the conventional digital controller at the time of abrupt changes in load and in input of a power amplifier. The digital controller is built in the power amplifier for supplying an output voltage vo to a load and is equipped with a manipulated variable calculating unit which detects the output voltage vo to calculate a manipulated variable ξ1 and a signal generating unit which converts the manipulated variable ξ1 into a signal for making the power amplifier operate. A feedforward function from an equivalent disturbance qy caused by the variation in the load is replaced by a feedback function from the output voltage vo and the manipulated variable ξ1, thereby allowing a transfer characteristic from the disturbance qy to the output voltage vo to result in a quadratic differential characteristic. Consequently, the variation in output voltage can be reduced as compared to the conventional controller at the time of the abrupt changes in the load and in the input of the power amplifier.

摘要： A process cartridge, and a main assembly of an image forming apparatus to which the cartridge is detachably mountable. The main assembly includes a motor, a driving rotatable member for receiving a driving force from the motor, and a twisted hole substantially coaxial with the driving rotatable member. The process cartridge includes an electrophotographic photosensitive drum, a process device actable on the drum, and a projection provided at a longitudinal end of the drum. When the driving rotatable member rotates with the hole and the projection engaged with each other, a rotational driving force is transmitted from the driving rotatable member to the drum through engagement between the hole and the projection with the projection being pulled into the hole.
