Title: One-component developing device
Inventor: KAMIYA YUTAKA
IPC: G03G15/09
Filed: 1985-04-15
Abstract: PURPOSE:To prevent foreign matter in a developer and a toner flocculate lump from staying on the upstream side of a doctor blade by separating the doctor blade from a sleeve intermittently. CONSTITUTION:The doctor blade 8 which extends in parallel to the axis of rotation of the developing sleeve fitted rotatably on a magnet holding shaft 4 is provided at the top of the sleeve 5 and the blade 8 is moved up and down through an electromagnetic plunger 9. When this plunger 9 operates to separate the blade 8 from the sleeve 5, the foreign matter 7 in the developer and the toner-flocculated lump pass under the blade 8 together with the developer 6. At this time, developing operation is stopped and a developing device 2 is rotated to separate a photosensitive body 1 and the sleeve 5 from each other, so that the developer 6a returns to a developer storage part smoothly. Thus, the foreign matter 7 in the developer and the toner-flocculated lump are prevented from staying on the upstream side of the blade 8.

The hardening state in the reaction of polyisocyanate is detected and the optimum timing of calendering is decided by measuring the amt. of nonreacted residual groups of polyisocyanate. This measurement is carried out by determining the amt. of NCO groups remaining in the curing agent and the amt. of CH groups in the binder resin with using an IR spectrophotometer. Thereby, the film has excellent dispersibility and is smooth and strong, and moreover, perpendicular orientation and noise characteristics can be improved.
