Abstract
An ejection condition determination method in an image forming apparatus includes: selecting two or more kinds of ejection conditions regarding other recording elements than a specified recording element among plural recording elements; acquiring drawing data representing two or more drawing patterns having different density distributions, the drawing data being acquired by respectively forming same drawing patterns using the selected two or more kinds of ejection conditions in a specified non-ejection state; performing a filter processing corresponding to human visual characteristics on the acquired drawing data so as to obtain visual correction drawing data; and determining the ejection conditions for compensating for a density variation of the image due to the specified non-ejection state based upon evaluation results which are obtained by respectively evaluating two or more drawing patterns represented by the visual correction drawing data and having been subjected to the filter processing according to a predetermined evaluation condition.
