Abstract: PURPOSE:To prevent the image flow of a photosensitive body of amorphous silicon by feeding magnetic toner to a magnetic roller through the photosensitive body according to the reflectance of toner on the roller and sticking it to the photosensitive body when a transfer material is not supplied. CONSTITUTION:The stuck quantity of non-magnetic toner is measured and detected based on the reflectance by a reflectance detecting sensor 7c provided near the magnetic roller 7b. When it becomes below the reflectance required for forming a magnetic brush, the magnetic toner is fed from a developing unit 4b through the photosensitive body 1 and the formation of the brush is secured. In this way, the magnetic toner is supplied to the roller 7b through the photosensitive body of amorphous silicon 1 according to the reflectance on the magnetic roller 7b and stuck to it. Thus, the magnetic brush needed for rubbing and grinding the photosensitive body 1 can be formed to be one having good response and also can be stably and economically formed by proper ly feeding neither too much nor too little magnetic toner. Besides, the occurrence of the image flow of the photosensitive body 1 and the fault of the image there of caused by the dripping of the non-magnetic toner can be eliminated.

Abstract: PURPOSE:To detect accurately the state of a pinhole of a chemical vapor-deposition film by processing a semiconductor substrate, which has a metal layer and the chemical vapor-deposition film stacked on its surface in sequence, in a chemical etching solution for the metal layer. CONSTITUTION:On semiconductor substrate 1, Al film 2 of approximately 1mu in thickness is formed and on it, silicon dioxide film 3 is also formed by chemical vapor deposition (CVD) [In this case, pinholes 4 may be made in silicon dioxide  film 3]. Next, when the above semiconductor substrate is dipped in hot liquid  phosphoric acid (approximately 150-155 deg.C), silicon dioxide reacts little upon phosphoric acid, but phosphoric acid having passed through pingoles 4 reacts on Al  film 2, so that expanded etching holes will be made in Al film 2 right under pinholes 4. Next, a buffer etching solution (a mixture of fluoric acid and ammonium  fluoride) is used to remove silicon dioxide film 3 by dissolving and then etching  holes 5 are observed through a microscope to detect and measure pinholes.
