Abstract: A developing device includes first and second developer carriers facing each other in a facing region, a regulating member that regulates a layer thickness of developer, and a separation member. The first and second developer carriers respectively include first and second magnetic members that are respectively magnetized with first and second facing magnetic poles having opposite polarities. The separation member separates the developer so that the developer is supplied toward the first and second developer carriers. The separation member is disposed such that distances between the separation member and the first and second developer carriers are the smallest in a region in which a magnitude of a combined magnetic field of the first and second magnetic poles locally decreases as compared with a case where at least one of the first and second developer carriers is independently disposed due to interaction between the first and second facing magnetic poles.

Abstract: A nonvolatile semiconductor memory device includes: a sense amplifier; bit lines coupled to the sense amplifier; memory cell transistors and dummy cell transistors coupled in parallel with the bit lines; and a current generating circuit that supplies a test current to current nodes. Either of the source and the drain of each of the dummy cell transistors is coupled to a bit line and the other is coupled to a current node. In a read operation test, the current generating circuit is activated and then the dummy cell transistors are turned on. The sense amplifier compares the test current passed through a bit line with a reference current and outputs output data corresponding to the result of the comparison.
