An image forming agent storage device includes an image forming agent storage body that is inserted into an insertion part, an opening-and-closing member, an engagement mechanism and an engagement release prevention mechanism. The image forming agent storage body is formed with a discharge port. The engagement mechanism includes an engagement part being provided in the image forming agent storage body and an engaged part being provided in the opening-and-closing member and being capable of engaging with the engagement part. The engagement release prevention mechanism prevents that a state where the engagement part and the engaged part can engage with each other is released due to an event that a front side of the opening-and-closing member moves relative to the image forming agent storage body so as to slant in a direction away from a position where the engagement part and the engaged part are provided. |
