Embodiment 1
[0102] figure 2 A tandem digital full-color printer serving as an image forming apparatus to which the image exposure apparatus and cleaning apparatus according to Exemplary Embodiment 1 of the present invention are applied is shown.
[0103] exist figure 2 Among them, reference numeral 1 represents the main body of a tandem digital full-color printer, and an image processing device (not shown) is provided inside the printer main body 1 for processing data from, for example, a scanner not shown, personal Predetermined image processing is performed on image data transmitted from a computer and / or telephone line.
[0104] Such as figure 2 As shown in , inside the main body 1 of the tandem digital full-color printer, four image forming units (image forming sections) of yellow (Y), magenta (M), cyan (C) and black (K) 2Y, 2M, 2C, and 2K are arranged in parallel at fixed intervals to be diagonally inclined at a predetermined angle (for example, 10 degrees) with respect to the ...

The present invention relates to an image exposure apparatus, an cleaning device of an image exposure apparatus, and an image forming apparatus using those. An image exposure apparatus includes: an optical unit that emits light to form an exposure image on a photosensitive material; a casing that houses the optical unit and that has an image exposure window through which the light is allowed to pass for forming the exposure image; a transparent dustproof member at the image exposure window; and a shutter member switched between a shield position for covering a region above the dustproof member, which serves as a passage region of a cleaning member for cleaning a surface of the dustproof member, and an open position for allowing the light to pass through the dustproof member to form an exposure image on a surface of the photosensitive material. When the shutter member is located at the shield position, at least a part of the shutter member goes into the passage region of the cleaning member.
Description
technical field [0001] The present invention relates to an image exposure device, a cleaning device for the image exposure device, and an image forming device using these devices. Background technique [0002] Conventional image forming apparatuses include an image forming apparatus formed such that an intermediate transfer belt is provided in each color of yellow (Y), magenta (M), cyan (C), and black (K). and an exposure image is formed on the photosensitive drum of each image forming portion by an image exposure device disposed below each image forming portion. [0003] Since an exposure image is formed on the photosensitive drum from below in the image exposure device used in such an image forming apparatus, the toner may drop from the photosensitive drum and / or the developing device, making such as Optical components such as mirrors of the image exposure unit may be contaminated. Therefore, the image exposure device is formed such that an exposure window made of a tran...
