Abstract: A toner concentration sensing apparatus includes a first acquisition processing portion, a second acquisition processing portion, and a third acquisition processing portion. The first acquisition processing portion acquires a first sensing value corresponding to light reflected by a first region of an image-carrying member where a toner image is not formed. The second acquisition processing portion acquires a second sensing value corresponding to light reflected by a second region of the image-carrying member where a toner image has been formed. The third acquisition processing portion acquires a component ratio of a component in the second sensing value, that corresponds to light reflected by toner adhered onto a surface of the image-carrying member, using a specific calculation formula determined based on a first relational expression based on the first sensing value and a second relational expression not based on the first sensing value, and the second sensing value.

Abstract: An image forming apparatus includes first to third adjustment processing portions. The first adjustment processing portion adjusts an emission light amount of a light-emitting portion of a first sensor based on an electric signal output from a light-receiving portion of the first sensor and corresponding to regular reflection light reflected by a non-toner-adhering surface of an image-carrying member. The second adjustment processing portion adjusts an operation condition of an image forming portion based on a toner concentration of a first toner image in a specific color, that has a concentration smaller than a predetermined saturation concentration. The third adjustment processing portion adjusts an emission light amount of a light-emitting portion of a second sensor based on an electric signal output from a light-receiving portion of the second sensor and corresponding to diffuse reflection light reflected by a second toner image in the specific color, that has a predetermined reference concentration.

Abstract: A movable member is gripped in a delamination-start configuration, and the other-end side of a rib of a delamination member is pressed towards the other-end side of a flexible plate. The flexible plate then warps and deforms about the other end side of the flexible plate, which is supported by a support member, the flexible plate deforming along the direction in which delamination progresses. In concert with the delamination action, a reinforcing plate also warps and deforms along with the flexible plate, the reinforcing plate being vacuum-chucked to an air-permeable electroconductive sheet on the flexible plate, and the reinforcing plate is sequentially delaminated from a substrate 2 along the direction in which delamination progresses.

Abstract: In a multiple data continuous write to a non-volatile memory, a write determination is performed by eliminating as much as possible the effect of the amount of threshold variation due to electron-hole recombination generated in a write operation of a memory cell. It is controlled so that a cycle (tw) of performing a write operation on a memory cell in a write operation and a cycle (tv+tw?tv) of performing a write verify operation on a memory cell in a write verify operation are the same. Alternatively, as address advances from a first address to the nth address (n is an integer) where continuous write is performed, a determination condition in the write verify operation is made severer.
