摘要： An image forming apparatus includes an image bearer, a charging device that charges a surface of the image bearer, a latent image forming device that forms a latent image on the image bearer, a developing device that develops the latent image on the image bearer with a spherical toner into a toner image, a transfer device that transfers the toner image to a transfer material, and a cleaning device that removes the spherical toner remaining on the image bearer after the toner image is transferred to the transfer material. The cleaning device including a cleaning roller that removes the spherical toner on the image bearer while rotating and contacting the image bearer and which has a greater coefficient of static friction than the surface of the image bearer. An electric field is formed between the cleaning member and the image bearer by applying a voltage to the cleaning member so that the spherical toner adhered onto the image bearer is electrostatically attracted to the cleaning member. The cleaning member may also include a brush roller having bristles planted in a specific configuration.

摘要： A charging device is provided. The charging device comprises a charging member having two spacers made of tape, and the charging member is pressed to contact with the non-image forming region of an image supporter. The surface of the charging member between the spacers is opposite to the surface of the image supporter by a tiny gap. A charging voltage is then applied to the charging member to charge the image supporter. As the image supporter rotates, a large variation of the tiny gap can be avoided. The pressing force of the spacers against the image supporter is set at 4 N to 25 N (Newton), and in a moving direction of the surface of the supporter, a contact width of a contact portion where the spacer is pressed to contact with the image supporter is set below 0.5 mm.

摘要： An image forming apparatus including an image carrier, a charger, an electrostatic latent image forming member, a developing member, a transferor, and a cleaning device. The electrostatic latent image forming member forms an electrostatic latent image on a surface of the image carrier charged by the charger. The developing member develops the electrostatic latent image formed on the surface of the image carrier with toner particles to form a toner image. The transferor transfers the toner image formed on the surface of the image carrier onto a recording medium. The cleaning device includes a fine particle supplier and an electrostatic cleaning mechanism. The fine particle supplier supplies fine particles onto the surface of the image carrier while an image forming operation is not performed. The electrostatic cleaning mechanism electrostatically removes a foreign substance adhered to the supplied fine particles from the surface of the image carrier.

摘要： An image forming apparatus including an image bearer; a nip forming member, a nip width changing device, a power source; and a controller. The controller switches between a first mode and a second mode according to a predetermined condition. In the first mode, a duty of the transfer bias is a first duty and a width of a transfer nip is a first width. In the second mode, the duty of the transfer bias is a second duty lower than the first duty and the width of the transfer nip is a second width greater than the first width. The duty is (T−Tt)/T×100% where T denotes one cycle of the transfer bias, and Tt denotes a time period, in which the transfer bias is on a transfer-directional side relative to a time-averaged value of the transfer bias, in the one cycle.
