    摘要： A lubricant applicator includes a solid lubricant, a lubricant applying member to apply the solid lubricant to a target object, a biasing member to bias the solid lubricant toward the lubricant applying member, and a regulating member to regulate the solid lubricant, which is biased toward the lubricant applying member by the biasing member, to prevent the lubricant from separating from the lubricant applying member by more than a predetermined distance. The regulating member is switchable between a regulating state for regulating the solid lubricant not to separate from the lubricant applying member by more than the predetermined distance and a non-regulating state.

    摘要： An image-forming apparatus includes an image-bearing device that holds an electrostatic latent image and a toner image thereon, and a developer container that contains and agitates a developer having at least a toner. The image-forming apparatus also includes a developer-bearing device that carries the developer to develop the electrostatic latent image on the image-bearing device, and a density sensor that detects an optical density of a surface of the image-bearing device and a toner image on the image-bearing device. Further, the image-forming apparatus includes a developer seal that seals the developer in the developer container, wherein the seal is disposed between the developer container and the developer-bearing device, and an actuator configured to actuate the developer container and the developer-bearing device. The image-forming apparatus still further includes a control device that determines whether the developer seal is removed according to information on the optical density of the toner image output by the density sensor.
