Problems solved by technology

[0004] However, there is also a problem that, when the image forming apparatus is constructed in this way, the conveying unit (conveyor belt) is shaken due to shaking of the cover relative to the main body frame (especially shaking in the width direction of the conveying belt) during the traveling of the conveying belt. Offset along the main scanning direction (width direction of the conveyor belt)
If such a positional shift occurs during full-color printing, the conveying position of the recording paper is slightly shifted for each color; therefore, there is a disadvantage that a shift occurs in color registration
Such a disadvantage is also prevalent in the image forming apparatus in which the intermediate transfer belt is mounted on the cover

Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below based on examples shown in the drawings. In the drawings, the letters "Y", "M", "C" and " K" is added after the reference number.

[0022] First, the overall structure of the imaging device 10 related to the present invention will be described. Such as figure 1 and figure 2 As shown, the image forming apparatus 10 includes a main body frame 12 detachably housing an image carrier (photoreceptor) 20 and a developing unit 16 , and a cover 14 for opening and closing the image carrier 20 and developing unit 16 . A transport unit 18 provided with a transport belt 34 for sucking and transporting the recording paper P is detachably mounted on the cover 14 .

[0023] The developing unit 16 includes: a charging roller 22 for uniformly charging the surface of the roll-shaped image carrier 20; a light cartridge 24 for irradiating the image carrier 20 with image light according to image data to form a latent...

Abstract

An image forming apparatus including: a conveyance unit including a belt member stretched across at least a drive roller and a driven roller and conveys a recording medium and a casing that axially supports the drive roller and the driven roller; a body frame disposed with an image carrier for transferring an image to the recording medium; and a cover to which the conveyance unit is attached, is pivotably attached to the body frame, and opens / closes off the image carrier. A first regulating portion against which an annular member placed on a shaft portion of the drive roller abuts when the cover pivots toward the body frame to close off the image carrier and a second regulating portion with which an engagement portion formed in the casing in a direction orthogonal to the axial direction of the drive roller engages are formed on the body frame.

Description

technical field [0001] The present invention relates to an image forming apparatus in which a cover is pivotally mounted on a main body frame, and in which a transport unit for transporting a recording medium and an intermediate transfer belt are mounted on the cover, an image is transferred from a photoreceptor (image carrier) onto the intermediate transfer belt. Background technique [0002] Conventionally, there is known an image forming apparatus in which a toner image formed on a photoreceptor (image carrier) or an intermediate transfer belt (belt member) is transferred / fixed on recording paper (recording medium) to form image. Among these image forming apparatuses, there is an image forming apparatus in which a cover is pivotally mounted on a main body frame provided with the photoreceptor or the intermediate transfer belt, and the photoreceptor or the intermediate transfer belt is moved by opening the cover. Tape exposure (for example, see Japanese Patent Applicatio...
