Title:
DEVELOPING DEVICE FOR ELECTRONIC PHOTOGRAPH PRINTING APPARATUS, NON-PICTURE PORTION TONER REMOVING DEVICE, ELECTRONIC PHOTOGRAPH PRINTING APPARATUS USING THOSE DEVICES, ELECTRONIC PHOTOGRAPH PRINTING METHOD, AND GLASS/CERAMIC PLATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/145212
Kind Code:
A1
Abstract:
Provided is a developing device for an electronic photograph printing apparatus, which
can exhibit stable performances and can improve printing qualities. The developing
device (5) of the electronic photograph printing apparatus (1) comprises a feed
route (37) at least one agitation/transfer roller (27) for agitating/transferring a
carrier and a toner to be charged in contact with the carrier, and a developing roller
(25) disposed on the side of a photosensitive element (3) in the feed route (37)
and having an outer surface (47) for adsorbing and circumferentially moving the
toner having stuck to the carrier, thereby to feed the carrier to an electrostatic latent
image of the photosensitive element (3) at a feed position. The developing device
(5) further comprises a recovery unit for recovering the carrier from the outer
surface (47) at a position on the downstream side of the feed position in the moving
direction of the outer surface (47), a recovery route (39) for transferring the
carrier recovered by the recovery unit, to circulate and feed the carrier to the
feed route (37), and a toner density adjusting device (35) disposed in the recovery
route (39) for adjusting the ratio between the carrier and the toner to be transferred
by the recovery route (39), to a predetermined value.
