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： In an image forming apparatus in which toner is fed to a developer unit from a toner storage container through toner conveying means provided between the toner storage container and the developer unit, the image forming apparatus comprises a toner remaining amount detector for detecting not more than a predetermined amount of toner in the toner storage container, a toner density detector for detecting the density of toner in the developer unit, and means for interrupting the image forming operation to feed the toner to the developer unit from the toner storage container through the toner conveying means when the amount of the toner in the toner storage container is larger than the predetermined amount and the density detected by the toner density detector is lower than a predetermined density. Comsequently, suitable measures can be taken when there occurs such a state that no toner exists in the toner conveying means between the toner storage container and the developing mechanism even if the toner exists in the toner storage container.

摘要： A liquid crystal device with a decreased temperature-dependence of response speed is obtained by using a liquid crystal composition having a temperature range where the composition assumes chiral smectic C phase. The temperature range of chiral smectic C phase includes a) a first temperature range where the liquid crystal composition shows a cone angle in chiral smectic C phase which increases on temperature decrease down to a mediate temperature, and b) a second temperature range, below the first temperature range, where the liquid crystal composition shows a cone angle in chiral smectic C phase which decreases on further temperature decrease below the mediate temperature.

摘要： A liquid crystal device is constituted by a pair of substrates each having thereon an electrode, and a smectic liquid crystal having a plurality of smectic liquid crystal layers disposed between the substrates. The smectic liquid crystal is disposed to form a first region wherein the smectic liquid crystal layers are aligned to have a layer inclination angle smaller than a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic or are aligned in a direction perpendicular to the substrates to form a bookshelf structure, and a second region wherein the smectic liquid crystal layers are aligned to form a chevron structure having a substantial layer inclination angle or having a layer inclination angle substantially equal to a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic. The liquid crystal device having the first an second regions described above is effective in improving a contrast ratio and a driven margin parameter.

摘要： A liquid crystal device is constituted by disposing a chiral smectic liquid crystal between a pair of substrates each provided with an electrode and a uniaxial alignment film. The chiral smectic liquid crystal is placed in such a quasi-smectic A alignment state that the liquid crystal molecules will have a single average molecular axis under no electric field application on a lower temperature side within chiral smectic C phase range, wherein the single average molecular axis can be confirmed as a position providing the darkest state when observed through cross nicol polarizers. Such a quasi-smectic A alignment state is effective in providing a liquid crystal device (or display apparatus) having an improved shock resistance and a good low-temperature storage properties.

Each of the upper and lower substrates has thereon an electrode for applying a voltage to the liquid crystal and a uniaxial alignment film. The alignment films on the upper and lower substrates are provided with uniaxial alignment axes which cross each other so that the direction of crossing of the uniaxial alignment axes from the lower substrate to the upper substrate is identical to the direction of helical twist in cholesteric phase of the chiral smectic liquid crystal, and the chiral smectic liquid crystal is disposed in such an alignment state that the liquid crystal shows a pretilt angle .alpha., a cone angle H, an inclination angle .delta. of SmC.sup.* layer, and an apparent tilt angle .theta.a satisfying relationships of: H .theta.a>H/2. The crossing direction may preferably have a polarity (taken as "positive" in clockwise direction and "negative" in anticlockwise direction) which is the same as the polarity of the spontaneous polarization of the liquid crystal.
