ABSTRACT:
Disclosed is an evaluation device of an optical writing device, comprising: the optical writing device; a light reception section; a drive section; and a control section to light each light emitting element in a previously set lighting pattern based on a light amount; to drive the drive section to move the light reception section to a position opposite to the light emitting element to be lit; to calculate characteristic data based on a light amount value of the light received by the light reception section; to calculate a first calculation value based on the characteristic data for each light emitting element; to calculate a second calculation value different from the first calculation value based on the characteristic data; to calculate a third calculation value based on the first calculation value and the second calculation value; and to instruct the display section to display the third calculation value.
