Abstract: A lubricant application apparatus including a lubricant application member and an elastic member. The lubricant application member applies lubricant to a lubricant receiving member moving in a given a surface movement direction. The elastic member contacts the lubricant receiving member in a counter direction with respect to the surface movement direction of the lubricant receiving member, and smoothes the lubricant applied on the lubricant receiving member. The elastic member is in contact with the lubricant receiving member at a contact area of the elastic member, in the counter direction. The elastic member is positioned in a downstream side of the surface movement direction of the lubricant receiving member with respect to the contact area of the elastic member. The elastic member is in contact with the lubricant receiving member at the contact area with a contact angle of 85 degrees or more.

Abstract: A positioning member defines a facing distance between a first rotating body and a second rotating body. The positioning member includes a fitting portion, a groove, and a restricting member. A fitted portion of the first rotating body is to be rotatably fitted into the fitting portion. The groove has a groove shape extending in a predetermined direction from an opening to an abutting portion. A shaft portion of the second rotating body is to be slidably movable in the groove. The restricting member restricts movement of the shaft portion in the predetermined direction in a state in which the shaft portion abuts on the abutting portion in the groove. The restricting member is detachably disposed on the groove.

Abstract: An image forming apparatus includes a rotatable image bearer, an exposure device, a development unit, an adjuster, and a magnetic member. The exposure device forms a latent image on a surface of the image bearer. The developing unit renders the latent image visible with developer including toner and carrier. The adjuster contacts each of the image bearer and the exposure device to regulate a distance between the image bearer and the exposure device. The magnetic member is arranged side by side with the adjuster in a direction of rotation of the image bearer.
