    • The present invention relates to a composite lens and a method for manufacturing the same, particularly to a composite lens in which a second lens component is coupled to a first lens component at part of a first surface, and intends to improve optical characteristics. 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).
    • 复合透镜及其制造方法技术领域本发明涉及复合透镜及其制造方法,特别是涉及在第一表面的一部分将第二透镜部件与第一透镜部件连接的复合透镜,旨在提高光学特性。 复合透镜(1)具有第一透镜部件(10)和第二透镜部件(20)。 第一透镜部件(10)具有包括第一透镜表面(13),围绕第一透镜表面(13)的外周表面(15a)和包括在外围表面(15a)中的环表面(17a)的第一表面和 围绕第一透镜表面(13),以及在第一透镜表面(13)的相对侧上的第二透镜表面(12)。 第二透镜部件(20)在由环形表面(17a)包围的第一表面的一部分处联接到第一透镜部件(10)。 环形表面(17a)位于第一透镜部件的从第二透镜表面(20)的第一方向从第一透镜表面(13)和外周表面(15a)之间的接合部分(14)突出的部分上 )沿着第一透镜部件(10)的光轴移动到第一透镜表面(10),并且暴露在第二透镜部件(20)之外。

    • A development device includes a developer carrier, a bearing member, a biasing member, and a guide. The developer carrier supplies a developer to an electrostatic latent image formed on an image carrier to develop the electrostatic latent image into a toner image. The bearing member rotatably supports the developer carrier axially. The biasing member is provided on a side of the bearing member opposite the image carrier to apply a force to the bearing member to move the bearing member and the developer carrier toward the image carrier. The guide is disposed about the bearing member to enable the bearing member to move therebetween and guide the bearing member toward the image carrier. The bearing member includes a rotatable part to rotate and slide over the guide while contacting the guide.
    • 显影装置包括显影剂载体,轴承构件,偏置构件和引导件。 显影剂载体将显影剂供给到形成在图像载体上的静电潜像,以将静电潜像显影成调色剂图像。 轴承构件可轴向地支撑显影剂载体。 偏置构件设置在与图像载体相对的轴承构件的一侧上,以向轴承构件施加力以将轴承构件和显影剂载体朝向图像载体移动。 引导件围绕轴承构件设置,以使得轴承构件能够在其间移动并将轴承构件引向图像载体。 轴承构件包括可旋转部分,以在接触引导件时在引导件上旋转和滑动。
