To improve precision in the injection amount of a fuel injection valve, the opening and closing action of a valve body must be performed quickly. In a structure in which the fluid force produced in a seat of a valve body is not transmitted immediately after a needle begins to move, adhesion between an end surface of an anchor and an end surface of a stationary core must be impeded and these end surfaces must be prevented from sticking together. To solve this problem, the present invention is a structure in which a valve body of an electromagnetic fuel injection valve comprises a second valve body in contact with the anchor when the valve is closed, and a first valve body in contact with the anchor while the valve is opening. The second valve body comes in contact with a stroke stopper disposed on the inner periphery of the stationary core when the valve opens, the lengths of the first valve body and the second valve body are stipulated so that the stationary core and the anchor do not come into direct contact and a gap is ensured when the valve opens, and the process of plating the stationary core and the anchor is discontinued.

The invention provides an image forming device. The drive transmission unit included in the image forming apparatus includes a first drive transmission unit and a second drive transmission unit. The first drive transmission unit transmits the rotational driving force of the motor rotating in the first rotational direction to the toner container, thereby conveying the toner contained in the toner container in a predetermined direction, and restricting the The rotational driving force of the motor rotating in the second rotational direction is transmitted to the toner container. The second drive transmission part transmits the rotational driving force of the motor rotating in the second rotation direction to the container cover, thereby changing the state of the container cover from the closed state to the open state, and restricting the movement to the container cover. The rotational driving force of the motor rotating in the first rotational direction is transmitted to the container cover.
