Abstract

An image forming apparatus includes an image forming device to form a toner image according to image data, a density adjustment toner pattern, and a timing adjustment toner pattern on an image bearer, a detector to detect the density adjustment toner pattern and the timing adjustment toner pattern, and an image density adjustment unit to execute image density adjustment based on an amount of toner adhering to the density adjustment toner pattern detected by the toner amount detector. The image density adjustment unit causes the image forming device to form the timing adjustment toner pattern before the density adjustment toner pattern is formed, and the image density adjustment unit adjusts a detection timing of the density adjustment toner pattern based on a detection timing of the timing adjustment toner pattern detected by the toner amount detector.
