摘要： A charger is provided. The charger includes a discharge electrode, a cleaner, and a holder. The discharge electrode is composed of a wire, and the wire has a surface plated with palladium. The cleaner removes foreign substances adhered to the discharge electrode. The cleaner includes a first cleaner composed of a glass-containing resin and a second cleaner. The first cleaner scrapes off the foreign substances by press-contacting the wire while moving, and the second cleaner wipes off the foreign substances by press-contacting the wire while moving. The holder movably holds the cleaner in a direction parallel to the discharge electrode.

摘要： An image forming apparatus includes an image bearer; a charger to charge a surface of the image bearer; an exposure device to expose the surface of the image bearer and form an electrostatic latent image on the image bearer; a developing device to adhere electrically charged toner to the electrostatic latent image on the image bearer, to thereby form a toner image; a microprocessor to control rotation of the image bearer; and a sensor to detect temperature and humidity. In a state of suspended rotation of the image bearer, the microprocessor controls the image bearer to rotate a predetermined amount at a predetermined interval and determines whether a rotation operation of the image bearer is to be performed, based on a detection result of the sensor.

摘要： A device disposed opposing an image bearer includes a roller to rotate while contacting a surface of the image bearer, a rolling bearing fitted around a shaft located at an end of the roller in an axial direction of the roller, a frame to house the roller, and a bearing support removably attached to the frame. The rolling bearing includes an outer ring, an inner ring, and a rolling element disposed between the outer ring and the inner ring. The bearing support holds, from an outer-ring side, the rolling bearing interposed between the bearing support and the frame. The bearing support includes a receiving portion to contact the outer ring of the rolling bearing and bias the rolling bearing toward the frame in a direction in which the rolling bearing is interposed between the bearing support and the frame.
