Provided is a method of manufacturing an electrostatic charge image developing toner exhibiting reduced variation in charging amount among manufacturing lots, which is capable of generating no fog, and acquiring high density print images. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw. An air cleaner, a suction pipe, a throttle body and an intake manifold are arranged substantially horizontally from a rear side portion of a motorcycle body towards a front side portion thereof so as to constitute an engine intake device to be connected to the engine. The difference between the value of the electrical parameter measured without exposure to light and the corresponding parameter measured with exposure to light is then established. The method includes establishing one-way communication between the local room and the remote room, transmitting the plurality of images of the caller to the remote room, displaying the plurality of images of the caller in real time on the remote viewscreen, and establishing two-way communication between the local room and the remote room.
