求の範囲第１項記載の画像形成装置。[Scope of Claim for Utility Model Registration] (1) An image forming device that guides a document image to a photoreceptor by moving an optical movable body to illuminate a document placed on a document placement plate, and , in an image forming apparatus configured such that a sliding member provided on an optical moving body slides on a guide rail extending in the moving direction of the optical moving body of the apparatus main body; an oil reservoir that is a concave portion and is arranged outside the illumination movement range of the optical movable body; a control means that moves the optical movable body so that a sliding member moves to the arrangement area of the oil reservoir at a predetermined timing; An image forming apparatus comprising: (2) The image forming apparatus according to claim 1, wherein the timing is when the number of times the optical movable body moves reaches a predetermined number of times. (3) The image forming apparatus according to claim 1, wherein the timing is when the moving distance of the optical movable body reaches a predetermined value. (4) The above timing is when the power is turned on.
An image forming apparatus according to claim 1 of the above-mentioned utility model registration claim. (5) The image forming apparatus according to claim 1, wherein the timing is when a predetermined period of time has elapsed from the end of a series of movements of the optical movable body. (6) The image forming apparatus according to claim 1, wherein the timing is a time of movement related to illumination movement of the optical movable body.
