An electrostatic screen printer includes: an electrically conductive screen arranged in non-contact with a printing medium; sponges for rubbing a powder into the screen; and a direct current power source for applying a voltage to the printing medium and the powder, wherein the powder rubbed into the screen is adhered to the printing medium by electrostatic induction. The electrostatic screen printer includes a rotation mechanism for rotating the sponges, a parent revolution mechanism for parent revolution of the sponges, and a child revolution mechanism for child revolution of the sponges. The revolution speed ratio of the child revolution to the parent revolution may preferably be 4.0 or greater, a scraper is provided on the parent revolution mechanism so as to be interlocked with the revolution of the sponges, and the scraper is arranged so as to scrape the powder on the screen toward an axis of the parent revolution

An image bearing structure includes an image drum including at least one slot, a plurality of ring electrodes formed on an outer circumference of the image drum, and a control board positioned within the slot of the image drum, and connected to the plurality of ring electrodes, to detect a defect of the ring electrodes. As a result, the image bearing structure detects a defect within a short time and without requiring a separate detecting device.

A pattern forming apparatus brings a masking panel having a pattern-like through hole into tight contact with the inside surface of a front panel, and positions the through hole to the inside of a recess of the front panel. In this state, liquid developer is supplied through a developing roller, and an electric field passing through a developing recess where the recess and through hole are continued. Therefore, charged developer particles are collected in the developing recess, and the recess of the front panel is developed.

A simple structure of a digital photosensitive drum having an exposure source and a photosensitive member which are integrated with each other. The drum is mountable to a structure of a conventional electrophotographic image forming process. An interval between phase detecting patterns of an encoder wheel portion which is rotated with the drum is equal to or smaller than an interval between a charging position and a developing position. During an image forming process, a timing for each pixel to be driven to emit light is controlled based on a phase detection value.

An electrostatic printing apparatus according to the present invention rubs powdery ink into a screen having a predetermined printed pattern formed therein, and applies a voltage between the screen and an object so as to attach the powdery ink to the object. A plurality of screens (34a-34d) are provided so that the plurality of screens are movable to a position located above the object (1). The plurality of screens (34a-34d) are provided so as to be rotatable about a shaft (46). The screens (34a-34d) are rotated about the shaft (46) to move the screens (34a-34d) to the position located above the object (1).

An electrophoretic display device including first and second substrates disposed with a predetermined spacing, a partition member disposed between the first and second substrates, a plurality of electrophoretic particles and an insulating liquid which are sealed up by the substrates and the partition member, and first and second electrodes disposed close to the insulating liquid, is produced through a production process comprising the following steps (A), (B), (C) and (D): (A) a step of filling the insulating liquid and the electrophoretic particles in a recess defined by the first substrate and the partition member, (B) a step of placing a first area of the second substrate to be in contact with the partition member in an uncured state and a second area of the second substrate to be in contact with the insulating liquid in a cured state, (C) a step of causing the first area of the second substrate to contact the partition member and the second area of the second substrate to contact the insulating liquid, and (D) a step of curing the first area of the second substrate contacting the partition member.
摘要:
An apparatus performs emboss-printing. The apparatus forms an image on a print supporting member, such as a paper sheet, by using a powder printing member. The charge characteristics of the image and the print supporting member are different from each other. Because of the different charge characteristics of the two members, a thermoplastic developing agent is selectively attached to either the image portion or the non-image portion of the print supporting member. The attached thermoplastic developing agent is heat-melted to form an embossed image.

Disclosed is a process for forming images which comprises applying a curable liquid to a first substrate in an image pattern, optionally transferring the curable liquid image to a second substrate, subsequently contacting the curable liquid image with a solid developer so that the developer adheres to the curable liquid image, optionally transferring the curable liquid and the solid developer in image pattern to a third substrate, and curing the curable liquid in the image pattern to a solid.

Disclosed is a method for producing an electro-photographic photoreceptor capable of repeated copying without one imagewise exposure for every one copying and which is superior in stability, sensitivity, resolution and tone reproduction. This method comprises converting to an insulator, by irradiation with energy ray, any selected area of a surface of an electrophotographic photoreceptor comprising a conductive substrate, a carrier generation layer and a carrier transport layer composed mainly of a compound which is converted to an insulator by irradiation with energy ray.
