Abstract: An image forming apparatus includes image forming devices, image output devices, an endless conveyor, a transfer device, holders, a detector, and circuitry. The image forming devices include image bearers. The image output devices form latent images on the image bearers. The image forming devices form visible images from the latent images. The transfer device transfers the visible images onto the endless conveyor that conveys the visible images in an image conveyance direction. The holders hold the image forming devices interchangeable at holding positions aligned in the image conveyance direction. The detector detects the visible images. The circuitry compares a first visible image of the visible images formed at a specific holding position of the holding positions with a second visible image of the visible images formed at another holding position of the holding positions on the endless conveyor, to correct misalignment between the first and second visible images.
Abstract: A method of evaluating a power storage device includes at least [a] to [f] below. [a] A power storage device is prepared. [b] A charge level of the power storage device is adjusted to produce a first potential difference between a positive electrode and a negative electrode. [c] The positive electrode or the negative electrode is selected as a reference electrode. [d] After the charge level is adjusted, an operation to insert a conductive rod-shaped member into a stack portion along a direction of stack of the positive electrode and the negative electrode is performed while a second potential difference between the reference electrode and the rod-shaped member is measured. [e] The rod-shaped member is stopped. [f] The power storage device is evaluated based on a state of the power storage device after the rod-shaped member is stopped.
