The image reading device reads an image of an object by moving an image capturing element in the predetermined horizontal direction when the image forming unit operates. Spring elements are provided between the image forming unit and the image reading unit to apply an urging force therebetween in a direction parallel to the predetermined horizontal direction. The spring elements satisfy the following condition:ffn>2,where, f and fnare characteristic frequencies of the image forming unit and the image reading unit, respectively, in the predetermined horizontal direction.
