    摘要： An inverse telescopic wide angle lens comprises a diaphragm; a front lens group of an integral positive or negative refractive power, positioned in the object side in front of the diaphragm and having a first lens group of a negative refractive power including a negative lens of which an image-side air-contacting surface is formed as an aspherical surface concave to the image side, and a second lens group of a positive refractive power positioned between the first lens group and the diaphragm; and a rear lens group of an integral positive refractive power, positioned behind the diaphragm and having plural lenses. The negative lens in the first lens group is so constructed that the absolute value of the refractive power of the concave surface on the optical axis is larger than that of the refractive power of the surface at the object side on the optical axis, that the curvature of the concave surface decreases monotonously with the distance from the optical axis, and that the form of the concave surface of the negative lens at the image side satisfies a particular condition. The effective diameter of the lens closest to the object in the first lens group is so constructed as to satisfy a particular condition.

    摘要： The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.

A composite lens (1) has a first lens component (10) and a second lens component (20). The first lens component (10) has a first surface including a first lens surface (13), a peripheral surface (15a) surrounding the first lens surface (13) and a ring surface (17a) included in the peripheral surface (15a) and surrounding the first lens surface (13), and a second lens surface (12) on the opposite side of the first lens surface (13). The second lens component (20) is coupled to the first lens component (10) at part of the first surface surrounded by the ring surface (17a). The ring surface (17a) is positioned on a portion of the first lens component protruding from a joint portion (14) between the first lens surface (13) and the peripheral surface (15a) in a first direction from the second lens surface (20) to the first lens surface (10) along an optical axis of the first lens component (10) and is exposed out of the second lens component (20).
