Abstract:
A controller controls a first image forming unit and a second image forming unit to form a test image having a pattern. The test image is formed by the first image forming unit based on a first image forming condition in which an absolute value of a developing potential of a first developing sleeve is greater than an absolute value of a charging potential of a first photosensitive member. The pattern is formed by a second image forming unit based on a second image forming condition in which an absolute value of a developing potential of a second developing sleeve is smaller than an absolute value of a charging potential of a second photosensitive member. A controller controls a sensor to read the test image having the pattern.

Claim (Index 1):
An image forming apparatus comprising:\n a first image forming unit configured to form a first image, the first image forming unit including a first photosensitive member, a first charging unit that charges the first photosensitive member, a first exposure unit that exposes the first photosensitive member to form an electrostatic latent image, and a first developing sleeve that develops the electrostatic latent image on the first photosensitive member by using a developing agent of a first color; a second image forming unit configured to form a second image, the second image forming unit including a second photosensitive member, a second charging unit that charges the second photosensitive member, a second exposure unit that exposes the second photosensitive member to form an electrostatic latent image, and a second developing sleeve that develops the electrostatic latent image on the second photosensitive member by using a developing agent of a second color different from first color; a transfer portion at which the first image and the second image are transferred onto a sheet; a sensor configured to read a test image formed on the sheet, the test image used for detecting a causal part of a streak occurring when an image is formed on the sheet by the image forming apparatus; and a controller configured to:\n control the first image forming unit and the second image forming unit to form a test image having a pattern,\n wherein the test image is formed by the first image forming unit based on a first image forming condition in which an absolute value of a developing potential of the first developing sleeve is greater than an absolute value of a charging potential of the first photosensitive member, and \n wherein the pattern is formed by the second image forming unit based on a second image forming condition in which an absolute value of a developing potential of the second developing sleeve is smaller than an absolute value of a charging potential of the second photosensitive member; and \n \n control the sensor to read the test image having the pattern.
