The memory cell has a pair of transistors having charge storage regions and arranged along a row direction of the memory cell array. Word lines are provided between the memory cells adjacent to each other along a column direction of the memory cell array and extend along the row direction. Bit lines are provided between the transistors adjacent to each other along the row direction and extend along the column direction. Gates of the pair of transistors constituting the respective memory cells are connected to each other and further connected to the word line corresponding to the relevant memory cell. Sources of the pair of transistors are connected to each other and further connected to the bit lines provided between the relevant pair of transistors. Drains of the transistors facing each other between the both memory cells adjacent to each other along the row direction are connected to each other and further connected to the bit line provided between the relevant adjacent memory cells. A pair of the bit lines connected to the both drains of the pairs of transistors included in all of the memory cells are connected to a comparison input terminal of the differential detector. An information retained in the memory cell is read based on a comparison result of current amounts inputted to the differential detector via the pair of bit lines obtained by the differential detector in a state where memory cell currents are simultaneously and independently supplied to the pair of transistors.

摘要： An image forming apparatus includes an image bearer, an image forming device, a toner concentration detector, a toner supply device, an image density detector, and a controller including a memory device. At a predetermined timing before image formation is started, the controller adjusts a developing potential to adjust an image density of a detection toner image on the image bearer and drives the toner supply device or the developing device to adjust a toner concentration in the developing device. After the image formation is started, the controller drives the toner supply device to adjust the toner concentration, and, in a predetermined sheet interval, adjusts the target concentration based on the image density of the detection toner image formed in a non-image area of the image bearer. When the toner concentration is higher than the target concentration plus a threshold, the controller suspends image formation and readjusts the developing potential.

摘要： An image forming apparatus includes multiple image forming units each including a latent image bearer and a developing device, a transfer device to transfer toner images from the latent image bearers onto a surface of endless rotary member, a cleaner to clean the surface of the endless rotary member, and a control unit to execute a forcible toner consumption process to forcibly consume degraded toner stored in applicable one or more developing devices. The forcible toner consumption process includes a step of forming a toner image formed for forced consumption in a non-image region of the latent image bearer with an amount of toner corresponding to a difference between an image area ratio of a developed image and a prescribed threshold when the image area ratio of the developed image is lower than the prescribed threshold.
