Title: Electrostatic developer and electrostatic developing method and image forming method
Inventor: MATSUBARA AKITOSHI
IPC: G03G9/08
Filed: 1986-12-19
Abstract: PURPOSE:To obtain good positive electrostatic chargeability and excellent moisture resistance by incorporating fine inorg. particles having amino group-contg. silicone resin or the cured matter thereof on the surface into a titled developer. CONSTITUTION:The fine inorg. particles having the amino group-contg. silicone resin or the cured matter thereof on the surface are incorporated into the electrostatic developer. More specifically, the amino group-contg. silicone resin or the cured matter thereof has three-dimensional network structure and, therefore, the fine inorg. particles having the amino group-contg. silicone resin or the cured matter thereof on the surface is coated with the uniform and secure film over the entire surface thereof. The possibility that the negative electrostatically chargeable site and hydrophilic site of the fine inorg. particles remain is small. The stable positive electrostatic chargeability is thus imparted to the developer even under high humidity environment.

Inventor: HONDA YOICHI
IPC: G01R33/032
Filed: 1990-11-13
Abstract: PURPOSE:To eliminate multiple components produced during measuring an alternating current magnetic field and improve sensitivity of a sensor by using a magnetic garnet plate having the Faraday rotation angle of 2npi during saturation of the magnetic field for the Faraday rotation element. CONSTITUTION:For the Faraday rotation element a magnetic garnet plate having the Faraday rotation angle of 2npi during saturation of magnetic field is used. As the magnetic garnet is constituted with two kinds of magnetic domain 9 having opposite magnetic direction to each other in the state with no external magnetic field, and the regions for each magnetic domain are equal. If a magnetic field in the direction of an arrow 11 is impressed, the region in the magnetic domain direction 11 as the magnetic field increases. As the Faraday rotation is proportional to the region difference of each magnetic domain and therefore to the impressed magnetic field, it saturates in an alternating current magnetic field over the saturated magnetic field. In the alternating current magnetic field below the saturation, the region of the two magnetic field varies periodically changing the rotation direction. With the magnetic field sensor using a magnetic garnet, the change in the light intensity reaching a light receiving element due to the region change is detected.
