Filed: 1988-06-03
Abstract: PURPOSE:To prevent generation of satellite dot and fog of recording image, and to record at a high speed by applying fine recording droplets flown when air bubbles are broken to a medium to be recorded and recording it. CONSTITUTION:Air bubbles 6 are generated near the outlet 5 of a passage 3 by air bubble generating means 2, and ink meniscus 7 is thus discharged from an outlet. When the bubbles are grown, the bubbles are broken, fine ink droplets 8 are flown, and recorded on a recording sheet.

Title: Image forming device using amorphous silicon photosensitive body
Inventor: UEDA SHIGENORI
IPC: G03G15/00
Filed: 1989-06-01
Abstract: PURPOSE:To shorten the first copying time by rotating the photosensitive body less than one revolution before latent image formation in the first copying, and controlling a paper feed time so that a part having an image through prexposure coincides with the leading edge of a transfer paper, in the image forming device using the amorphous Si photosensitive body. CONSTITUTION:Electrostatic latent images are formed on a photosensitive body surface in sequence by uniformly electrifying the photosensitive body to a prescribed potential by means of a corona-electrifier 3 and by exposing it. A developing device 6 carries out toner development, and an electrifier 7 discharges corona to improve separation. Each transfer paper set in cassettes 8 and 9 and a deck 10 reaches a roller 14 by means of rollers 11, 12, and 13, respectively. The roller 14 is driven so as to match the time that the point E of a photosensitive surface reaches a point F after an exposure device 2 is lit, therefore the leading edge of the transfer paper reaches the point F. After that, transfer fixing and ejection of the paper, on which an image is formed, are carried out. The roller 14 is controlled only in first copying or in a single mode copying. Since the amorphous Si photosensitive body is used, previous history is eliminated during stop, and does not affect the subsequent copying; the time first copying requires can be shortened because the photosensitive body has less than one prerotation.
