An image forming apparatus, including: an image forming unit configured to form toner images on an image bearing member and toner patterns for detecting a relative position of the toner images; a detection unit having a light emission unit and a light receiving unit configured to receive reflection light from the image bearing member and the toner patterns to output an analog signal; a conversion unit configured to convert the analog signal into a digital signal based on a threshold value; a correction unit configured to correct a misregistration between the toner images on a recording medium based on the digital signal; and a control unit configured to control, when values of the analog signal includes a value lower than the threshold value, light intensity of the light emission unit so that the values of the analog signal become higher than the threshold value. |
