Abstract
An image forming apparatus includes a detection unit to detect a toner attached to an image carrying surface at a detection position. The first control unit controls the image forming unit such that a first check image including a patch pattern and a line pattern is formed. The relationship determination unit determines a correlation between a width of the line pattern and a density of an image to be formed based on a density of the patch pattern and a width of the line pattern. The determination unit determines an allowable range based on the determined correlation. The second control unit controls the image forming unit such that a second check image including the line pattern is formed. The line width determination unit determines a width of the line pattern based on a detection status relating to the line pattern. The monitoring unit monitors a formation status of the image by comparing the determined width and the determined allowable range.
