Abstract
An image-forming apparatus includes a rotary body, an image-forming unit, at least two sensors, and a control device. The image-forming unit performs an image-forming operation. The at least two sensors read an image formed on the rotary body. The control device is configured to: control the image-forming unit to form a test image on the rotary body; control the sensors to read the test image formed on the rotary body to acquire at least two values each relating to one of the at least two sensors; calculate a weighted average value of the at least two values by using weightings that are assigned to the at least two values, respectively, one of the weightings being different from another of the weightings; and correct the image-forming operation using the weighted average value.
