Abstract:
1. An image forming apparatus that uses an image-adjusting pattern image to determine an image forming condition, the apparatus comprising: a detector adapted to detect information about an image-adjusting pattern image fixed onto a sheet; a fixing temperature detector having a plurality of sensors adapted to detect temperatures of a plurality of points in the axial direction of a fixing roller of a fixing section, wherein the fixing section is adapted to fix the image-adjusting pattern image onto the sheet; and a controller adapted to set, based on temperature detection values detected by the fixing temperature detector, a detection area in a place of the detector where the temperature is equal to a desired temperature, wherein the detection area is an area where the detector detects information about the image-adjusting pattern image, and use the information detected in the detection area by the detector to determine the image forming condition.
