    • In an image forming apparatus in which positioned below a development unit for accommodating a toner is an exposure unit that writes to a photosensitive drum by exposing an electrostatic latent image, an aperture portion on an upper surface of an exposure unit case positioned in an optical path of light from the exposure unit is provided so as to not become an impediment to the optical path of the light and a glass plate is inclined and provided on the aperture portion. An inclination angle of the glass plate is set to an angle inclined 40° with respect to a horizontal line so as to be greater than a repose angle of the toner when the toner has poor fluidity under a condition of high temperature and high humidity.
    • 在位于用于容纳调色剂的显影单元下方的图像形成装置中,是通过曝光静电潜像而向感光鼓写入的曝光单元,位于光路中的曝光单元壳体的上表面上的开口部分 设置来自曝光单元的光,以便不会成为光的光路的障碍,并且玻璃板倾斜并设置在孔部上。 相对于水平线,将玻璃板的倾斜角度设定为倾斜40°的角度,以便在调色剂在高温高湿的条件下具有差的流动性时,大于调色剂的休止角。

    • Provided is an image forming apparatus support structure which permits improvements in both strength and dimensional accuracy, and which can also accommodate increases in size. Because respective coupling member(s) and steel channel of respective post member(s) may be sequentially and individually connected, it is possible to improve support structure dimensional accuracy, it being possible to assemble support structure(s) such that deviation(s) in the respective coupling member(s) and the respective post member(s) offset(s) one another. Furthermore, steel channel is suitable for supporting load(s) in vertical direction(s). Moreover, respective coupling member(s) may serve as brace(s) when interposed between respective post members. Where this is the case, strength of the overall support structure may be made extremely high, and strain exhibited by the overall support structure may be reduced.
    • 提供了一种图像形成装置支撑结构,其允许改进强度和尺寸精度,并且还可以适应尺寸的增加。 由于相应的支柱构件的相应的联接构件和钢通道可以顺序地和单独地连接,所以可以改进支撑结构的尺寸精度,可以组装支撑结构,使得偏差 在相应的联接构件和相应的柱构件中彼此偏移。 此外,钢通道适用于在垂直方向上支撑负载。 此外,相应的联接构件可以在相应的柱构件之间插入时用作支架。 在这种情况下,总体支撑结构的强度可能变得非常高,并且整个支撑结构的应变可能会降低。
