摘要： A transfer unit of an image forming apparatus includes a transfer device, a pressing member, and a regulative member. The transfer device is provided adjacent to a photoconductor of the image forming apparatus and is separable from the photoconductor under its own weight. The pressing member presses the transfer device against the photoconductor. The regulative member regulates the distance by which transfer device is separated from the photoconductor when the pressing member disengages the transfer device therefrom. In this transfer unit, if a printing sheet is large, the pressing member disengages the transfer device after a given transfer operation. As a result, the transfer device separates from the photoconductor under its own weight, with the distance separating the transfer device from the photoconductor being regulated by the regulative member. Then, the transfer device idles in the separated state, wherein preparation for a subsequent transfer operation is made. In this manner, the transfer device is idled simply by regulating the movement of the transfer device through means of the regulative member. Consequently, little distortion occurs to the transfer unit support frames, and deterioration of the quality of the transferred images is thus checked.

摘要： A nipping device is provided in a transfer unit having a fixed support and rotating element rotatably supported by the fixed support. The nipping device retains a printing sheet against the circumferential surface of the rotating element, and separates the printing sheet from the transfer unit. The nipping device includes a nipper, a pivoting lever device and a drive device. The nipper is disposed pivotally on the circumferential surface of the rotating element, and retains the feed-leading edge of the printing sheet. The levers of the pivoting lever device are disposed within the rotating element, pivotal on an axes intersecting the circumferential surface of the transfer unit, and functions therein to open and close the nipper by which the printing sheet is nipped against and separated from the transfer unit. The drive device is disposed in the fixed support, and functions to turn the pivoting levers. Due to the structure of this device, it is possible to impel the pivoting levers in a uniform direction by the use of tension springs, and furthermore the setting of the impelling force of the springs to the minimum necessary, is facilitated, such that the load applied to the driving system of the transfer unit can be reduced.

摘要： A supporting apparatus for optical unit having an optical unit to expose an original set on a contact glass, a reciprocatingly movable supporting frame body equipped with the optical unit, a sliding member provided on both ends of the supporting frame body, and an eccentric cam mechanism provided on one end of the supporting frame body to vertically adjust one of the sliding member. By operating the eccentric cam mechanism, one end of the supporting frame body can be adjusted to a desired height so as to enable to adjust horizontality of the optical unit mounted on the supporting frame body. Furthermore, because a large gap is provided between a pair of sliding members provided on one end of each supporting frame body and the ends of the two supporting frame bodies where the sliding members are mounted are mutually disposed at reverse side, both supporting frame bodies can be caused to come as close at their home positions as possible.

摘要： An image forming apparatus includes an image supporting member; an exposure device for forming a static latent image on the image supporting member; a developing device for developing the static latent image formed on the image supporting member; an image control unit for controlling a condition for forming an image; and a density sensor for detecting a developer density. In the image forming apparatus, a first pattern for detecting the developer density is formed to determine whether the developer density is proper. When the developer density thus detected is greater than a threshold value, a second pattern for discarding developer is formed to discard the developer. A third pattern for density correction is formed to perform the density correction.
