    Abstract: An image forming apparatus having: an image supporting member; a developing device configured to supply a developer to the image supporting member to develop a latent image; a transfer member configured to transfer the developed image from the image supporting member to a transfer medium; a blade configured to remove the developer left on the image supporting member after transfer therefrom; a storing member located downstream from the transfer member and upstream from the blade, the storing member configured to temporarily store a part of the developer left after transfer therein; and a control unit. The storing member is controlled by the control unit to release the temporarily stored developer therefrom toward the image supporting member after a lapse of a predetermined time from when an image density of an image to be formed becomes lower than a predetermined value.

    Abstract: A charger includes a charging roller and a support portion which rotationally supports the charging roller. The charging roller includes a first region which is opposed to the support portion and a second region which is not opposed to the support portion. The charging roller includes a conductive shaft, an end part cover portion which is in contact with and covers the conductive shaft in a portion corresponding to the first region and is in slide contact with the support portion, and a high-resistance coating which is in contact with and covers the conductive shaft in a portion corresponding to the second region and abuts on a charged object. An inner end portion of the end part cover portion is covered with the high-resistance coating, and a thickness of the high-resistance coating is equal to or greater than a thickness of the end part cover portion.
