Abstract

PURPOSE: To improve developing efficiency and the quality of images by so constituting the device that the developing solution flows at relatively high velocity of flow without staying anywhere and that recording paper thoroughly closely adheres to a guide plate.
CONSTITUTION: When the developing solution is blown into a recording guide path 8 from a developing solution blow-out nozzle 7 and when recording paper is admitted into the path 8 by lead-in rollers 3, the developing solution flows at the velocity of flow higher than the conveying speed of the recording paper because the guide plate 4 inclines downward; in addition, the adjacent parts of the guide plates 4 and 5 are made vacant and therefore the developing solution flows smoothly. Moreover, the guide plates 4 and 5 are not electrically grounded. Hence, the static charge of the same polarity as that of toner particles is induced in the guide plates 4, 5 by the latent image charge of the recording paper, and the toner particle are repulsed from the ground part of the recording paper. Even more, the recording paper is placed on the upward facing guide plate 5 from the downward facing guide plate 4, hence it is thoroughly closely adhered. With such constitution, the developing efficiency is improved, and the flow of images and the like are prevented, whereby the quality of image is improved.
