Abstract:
An image forming apparatus including: a photosensitive member; a charging unit; an exposure unit; a developing unit; a transfer unit; and a controller configured to control the photosensitive member, the charging unit, the exposure unit, the developing unit, and the transfer unit to form a measurement image on the sheet, and acquire read data on the measurement image output from a reading device, wherein the measurement image includes a first measurement image and a second measurement image, wherein the controller forms the first measurement image based on a first image signal value and forms the second measurement image based on a second image signal value different from the first image signal value, and wherein the controller detects a streak included in the first measurement image or the second measurement image and determines an error based on a detection result.

Claim (Index 4):
The image forming apparatus according to  claim 1 , wherein when a density of an edge area of the streak is lower than a density of an area where the streak is not detected in the measurement image, the controller compares the density of the edge area of the streak with a density of other area different from the edge area of the streak, and\n wherein when the density of the other area is higher than the density of the edge area, the controller detects the error of the developing unit.
