Title:
METHOD FOR REMOVING IMAGE FORMING SUBSTANCES FROM IMAGE PRESERVING BODY AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH07110643
Kind Code:
A
Abstract:

PURPOSE: To provide an image forming substance-removing method and a device therefor which is capable of the recovery treatment even when all the image forming substances cannot be removed from an image preserving body with the image forming substance-peeling operation of one time, and enables the satisfactory removal of the image forming substances even when the image forming substances stuck on the image preserving body are large in quantity.

CONSTITUTION: When toner is left unremoved on a transferred paper sheet 10 after the 1st peeling treatment is executed, the rotational speed of coating rollers 207a and 207b is raised above the rotational speed level at the time of the 1st peeling treatment, then the liquid-imparting treatment is executed and thereafter, the peeling treatment is repeated. When the rotational speed of the coating rollers 207a and 207b is raised, a penetration promoting liquid 21 and a processing liquid 20 in larger quantities than those at the time of the preceding liquid-imparting treatment are supplied to the transferred paper sheet 10, thereby making the unremoved toner more unstable than the unremoved toner at the time of the preceding peeling treatment, and thus the toner is easily peeled off from the surface of the transferred paper sheet 10. Consequently, the toner is completely removed from the transferred paper sheet 10 while minimizing damage to the surface of the transferred paper sheet 10.
