Abstract

An image forming apparatus (10) and an image forming method (S10-S20) that form an image where occurrence of concentration unevenness caused by occurrence of mechanical crosstalk is suppressed are provided. According to the present invention, the distance from the boundary position of the inkjet head (200) corresponding to the concentration boundary (306A) between the first concentration region (302) and the second concentration region (304) to the second concentration region end (312) of the inkjet head is less than the reciprocal of the spatial frequency of the concentration unevenness. Accordingly, the length of the part in the first direction where the inkjet head forms the second concentration region is less than one period of the concentration unevenness. Even if crosstalk due to vibrations of the part where the inkjet head forms the first concentration region occurs, the visibility of the concentration unevenness occurring in the second concentration region can be reduced.
