ABSTRACT:
Provided is an image forming apparatus that not only prevents leakage of a developer from a developing apparatus due to vibrations and the like at the time of transportation but also enables attachment of a developer leakage preventing member to a miniaturized image forming apparatus and facilitates attachment and detachment of the developer leakage preventing member at the time of use of the image forming apparatus. The image forming apparatus that is shipped with a developing member being fitted to an apparatus main body includes a developer leakage preventing member that prevents leakage of a developer from the developing member, in which the developer leakage preventing member is fitted at an attachment position opposing the developing member in place of a component that is detachably attachable to the apparatus main body at the attachment position.
