    • A color image recording apparatus includes a mechanism that switches a plurality of image forming sections between image forming positions where the photoconductive drums are in contact with a transport belt and non-image forming positions where the photoconductive drums are not in contact with the transport belt. A pair of slide links extend and are slidable in a direction in which the image forming sections are aligned. Each of the slide links has first guide surfaces and second guide surfaces. When the image forming sections are at the image forming positions, supporting shafts of corresponding one of image forming sections rest on the first guide surfaces. When the image forming sections at the non-image forming positions, the supporting shafts of corresponding one of image forming sections rest on the second guide surfaces.
    • 彩色图像记录装置包括在感光鼓与传送带接触的图像形成位置和感光鼓不与输送带接触的非图像形成位置之间切换多个图像形成部的机构。 一对滑动连杆沿图像形成部对准的方向延伸并且可滑动。 每个滑动连杆具有第一引导表面和第二引导表面。 当图像形成部分处于图像形成位置时,相应的一个图像形成部分的支撑轴搁置在第一引导表面上。 当在非图像形成位置处的图像形成部分时,相应的一个图像形成部分的支撑轴搁置在第二引导表面上。

    • A guide member is disposed between a transferring section and a fixing section. The guide member has an upstream end and a downstream end with respect to the direction of travel of the recording medium. First and second guide members define a path therebetween in which the recording medium passes to the fixing section. The first guide member is formed with a plurality of ribs formed at intervals and aligned in a direction either transverse or parallel to the direction of travel of the recording medium. The ribs extend substantially from the upstream end to the downstream end and increase in height from the surface of each guide as the downstream end is approached and guide a leading end of the recording medium. The ribs may extent progressively outwardly as the downstream end is approached. The first guide member is supported so that it is pivotal on an axis perpendicular to the direction of travel of the recording medium. The first guide member can be moved between an operative and a non-operative position. The first guide member can receive a voltage of the same polarity as the toner image.
    • 引导构件设置在转印部分和定影部分之间。 引导构件相对于记录介质的行进方向具有上游端和下游端。 第一和第二引导构件在其间限定其中记录介质传递到固定部分的路径。 第一引导构件形成有多个肋,间隔地形成并且在横向或平行于记录介质的行进方向的方向上对齐。 当下游端接近并且引导记录介质的前端时,这些肋基本上从上游端延伸到下游端,并且从每个引导件的表面高度增加。 当下游端接近时,肋可以逐渐向外扩展。 第一引导构件被支撑成使得其在垂直于记录介质的行进方向的轴上枢转。 第一引导构件可以在操作位置和非操作位置之间移动。 第一引导构件可以接收与调色剂图像相同极性的电压。
