摘要:
An image recording method using a reversible thermosensitive recording material which is capable of assuming a transparent state when heated to a first temperature which is above room temperature, and a colored state when heated to a second temperature which is higher than the first temperature and then cooled, and a heating element, including the step of applying energy to the heating element for generating heat in such a manner as to form each picture element of an image to be formed in the recording material by a plurality of energy pulses applied thereto. An image recording apparatus for this image recording method is also described, which includes a pulse division device for dividing the energy to be applied to the heating element into the plurality of energy pulses, an ambient temperature measurement device for measuring the ambient temperature around the recording material, and a pulse-generation timing adjustment device for adjusting the timing for the generation of the plurality of energy pulses.

摘要:
An apparatus for recording data in a thermosensitive recording medium at a first temperature after erasing data written in the medium at a second temperature. The apparatus desirably erases data stored in a recording medium with no regard to the time elapsed after writing, condition of storage, writing conditions, the number of repetitive writing and erasing operations, etc.
摘要:
A recording apparatus for recording data in a thermosensitive recording medium. The recording medium has a reversible thermosensitive recording material capable of selectively assuming one of two visible states, e.g., a cloudy state and a transparent state or a colored state and a decolored state when heated. The thermosensitive material is applied to a sheet of resin. The apparatus surely erases data written in the medium with no regard to the time elapsed and the number of times that data has been repetitively written. The cloud density or the color density is prevented from changing with no regard to the storage temperature, the time elapsed, or the number of times of writing, thereby preventing image quality from being degraded. In addition, the medium has a long service life.
摘要:
A tandem image forming device for an image forming apparatus of the present invention includes a plurality of image forming means arranged side by side along an intermediate image transfer belt. The image forming means each include a developing device and a cleaning device arranged around an image carrier. One of nearby image forming means has its cleaning device positioned above the developing device of the other image forming means, e.g., an agitating section forming part of the image forming means. This configuration insures smooth circulation of a developer and therefore obviates an irregular developer distribution while reducing the overall size of the image forming device.
摘要:
An image forming apparatus of the present invention includes a casing, an image forming unit, and an air conditioning device. The image forming unit includes a case accommodating at least a photoconductive element therein and formed with an opening for image transfer via which the photoconductive element is partly exposed to the outside. The opening is the only opening that might allow substances harmful to image formation into the case when the image forming unit is mounted to the casing. The air conditioning device removes the harmful substances flowing into the image forming unit from the outside.
摘要:
An excess toner removal area is made broader over the whole area with respect to a developer applied area that is broader than an image effective area. Thereby a liquid developer, that tends to spread slightly broader than the applied area after being applied to a photoreceptor drum, is removed by a sweep roller that can sweep excess toner present in an area broader than the original applied area and an excess toner remaining area is then prevented from being formed on the photoreceptor drum. Accordingly, the excess toner on the latent image carrier is removed as much as possible, and a transfer medium and peripheral members are prevented from being soiled due to residual excess toner.

In an image forming apparatus, a fixing device fixes a toner image transferred to a sheet, but held in an unstable state, temporarily on the sheet by a Johnson Rahbeck effect. The fixed image firmly adhere to the sheet and is free from disturbance or suffers from a minimum of disturbance.
