Abstract
An image forming apparatus includes an image forming unit, an image bearer movable in a moving direction, a transferor, a cleaner, a sensor, and circuitry. The circuitry controls the image forming unit to form multiple toner patches arranged at a first interval on the image bearer in an orthogonal direction orthogonal to the moving direction and controls the sensor to detect the multiple toner patches. The circuitry adjusts the image forming unit based on a detection of the multiple toner patches by the sensor as an adjustment operation. The circuitry is configured to separate the transferor from the image bearer during the adjustment operation and control the image forming unit to form multiple patterns arranged at a second interval in the moving direction. Each of the multiple patterns has a band shape extending in the orthogonal direction.
