Title:
PRESSURE DEVELOPING DEVICE FOR IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JPH0425840
Kind Code:
A
Abstract:

PURPOSE: To reduce pressurizing force, to moderate impact at the time of starting and finishing pressurizing and to miniaturize a device by using a pressurizing member in which plural globular bodies are disposed.

CONSTITUTION: After image exposure is executed to a photosensitive film which is coated with a specified microcapsule, the film is superposed on a transfer paper, which are pressurized by the pressurizing member so as to form the image on the transfer paper. In such a case, plural holes are formed on a sleeve 101, and pressurizing is performed by using a member A obtained by disposing the globular bodies 102 to the holes. Since an area for pressure development becomes small by thus doing, the impact by the end of the transfer paper at the time of starting and finishing the pressure development becomes small. It is desirable that the globular body 102 does not pressurize a member to be pressurized when the member A does not rotate and a developing width by the globular body 102 is changed in accordance with the width of the transfer paper.
