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： An electric charging-diselectrifying device includes an electric charging member that contacts an image bearer to form an electric charging nip between the electric charging member and the image bear. The electric charging member electrically charges multiple electric charge regions in the image bearer located both upstream and downstream of the electric charging nip in a direction of rotation of the image bearer. An electric charge removing device is provided to remove electric charge borne on the image bearer by irradiating the multiple electric charging regions of the image bearer with light. The electric charging member is made of a material that allows the light emitted from the electric charge removing device to penetrate the electric charging member.

摘要： A charging device includes a charger and a power supply circuit. The charger is disposed opposing a latent image bearer. The power supply circuit applies to the charger an alternating voltage obtained by superimposing a pulsating voltage on a direct-current voltage. The alternating voltage generates normal discharge from the charger to a surface of the latent image bearer and reverse discharge from the surface of the latent image bearer to the charger. A pulse ON time of a voltage component toward a reverse discharge side relative to a desired surface potential Vde of the latent image bearer is shorter than a pulse ON time of a voltage component toward a normal discharge side relative to the desired surface potential Vde of the latent image bearer.

摘要： An image forming apparatus includes an image bearing member to bear a toner image, a waste toner storage mechanism to store residual toner, and an intermediate transfer unit detachable from the image forming apparatus. The intermediate transfer unit includes an intermediate transfer member onto which the toner image is transferred, a cleaning device to remove residual toner remaining on the intermediate transfer member after the toner image is transferred to a recording medium, and a connecting mechanism to connect the cleaning device and the waste toner storage mechanism. The connecting mechanism includes a movable connecting tube and a moving device to move the connecting tube between a first position at which the connecting tube engages the cleaning device and the waste toner storage mechanism, and the second position at which the connecting tube separates the cleaning device from the waste toner storage mechanism.

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： A charging device is detachably attachable with respect to a body of an image forming apparatus. The charging device includes a charging roller and a cleaning member. The charging roller charges an image bearer. The cleaning member cleans the charging roller. The cleaning member has a higher cleaning performance on the charging roller during detachment in which the charging device is detached from the body of the image forming apparatus than during attachment in which the charging device is attached to the body of the image forming apparatus.
