摘要： 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.

摘要： A transfer device includes an image bearing member, a transfer member, a test image detector, and a shield member. The image bearing member bears a toner image on a surface thereof within an image forming area. The transfer member disposed opposite the image bearing member forms a transfer nip between the transfer member and the image bearing member through which the recording medium is conveyed and transfers the toner image from the image bearing member onto the recording medium in the transfer nip. The test image detector disposed downstream from the transfer nip in the direction of conveyance of the recording medium detects a density of a test image for adjustment of toner density formed outside the image forming area. The shield member disposed between the test image and the transfer member shields the test image from an electrical field generated between the image bearing member and the transfer member.

摘要： A brake disk mounting surface is ground by bringing it into contact with an annular grinding wheel, while an inner ring having the brake disk mounting surface is rotated around its center axis, in a state where a part of the annular grinding wheel overlaps with a recess over an entire region of the annular grinding wheel in a radial direction, and in a state where a grinding surface of the annular grinding wheel is inclined with respect to the brake disk mounting surface so that a distance between the brake disk mounting surface and the annular grinding wheel grows larger in a direction toward an outer edge of the brake disk mounting surface.

摘要： After an image forming operation is finished, a motor that drives a belt is stopped after a predetermined time period passes since a sensor detects the only one mark provided on the belt. The predetermined time period is different for first, second and third job. This is repeated for the jobs thereafter. One job is a series of processing from the start of the motor to the stop of the motor. Thus, the belt stops at three different position for each consecutive three jobs.

摘要： An image forming apparatus includes a latent image bearer, an electric charging member to electrically charge the latent image bearer uniformly while forming an electric charging nip therebetween by contacting the latent image bearer. A value obtained by dividing a moment of inertia of area of the latent image bearer by the cube of length thereof ranges from about 0.000058 [mm] or more to about 0.000145 [mm] or less. A width of the electric charging nip in a direction of rotation at longitudinal ends of the latent image bearer is larger than that at a longitudinal center thereof. A difference between the width of the electric charging nip in the direction of rotation at the longitudinal ends of the latent image bearer and that at the longitudinal center thereof is larger than an amount of deformation of the latent image bearer generated during rotation at the longitudinal center thereof.
