摘要： In an image forming apparatus, a photoconductor and a charge roller are in contact with each other and configured to rotate together at linear velocity v (millimeters/second). In this structure, a DC voltage is applied to the photoconductor and the charge roller while they are not rotating. In this state, parameters such as voltage, linear velocity, pressure contact force between the photoconductor and the charge roller are selected so that the ratio w/v (seconds), where w is the interval between two discharge marks occurring on surface of photoconductor, is between 0.005 to 0.035.

摘要： An image forming apparatus includes a charger, a developing device, a cleaning device, a protective-agent bar, and a brush. The charger uniformly charges an image carrier. The developing device develops an electrostatic latent image formed on the image carrier to obtain a toner image as a visual image. The cleaning device removes toner remaining on the surface of the image carrier from which the toner image has been transferred onto a transfer material. The protective-agent bar contains a protective agent. The brush comes in contact with the protective-agent bar and the image carrier while rotating such that the protective agent adheres thereto and is supplied to the image carrier in an irregular form.

摘要： An image forming apparatus includes an image carrier, a charging device configured to uniformly charge a surface of the image carrier with a charging member applied with a bias of a first polarity (e.g. a negative polarity) for charging. A latent image forming device forms a latent image on the surface of the image carrier uniformly charged. A developing device develops a latent image by depositing toner grains of the first polarity on the latent image to thereby form a corresponding toner image. A transferring device forms an electric field between the image carrier and a moving member that serves as a movable contact with the image carrier to thereby transfer the toner image from the surface of the image carrier to the moving member or to a recording member nipped between the image carrier and the moving member. A polarity controlling device sets residual toner to a second polarity (e.g. a positive polarity) opposite to the first polarity, before the residual toner left on the image carrier by the transferring device is conveyed to a corresponding position to the charging member.

摘要： An image forming apparatus includes an image carrier, a developing unit, a concentration sensor, a toner supplying unit, a developer supplying unit, an ejector, and a condition detector. The image carrier forms a latent image thereon. The developing unit develops the latent image formed on the image carrier with a two-component image developer including toner particles and carrier particles. The concentration sensor detects a toner ratio in the developing unit. The toner supplying unit supplies fresh toner particles to the developing unit. The developer supplying unit supplies fresh image developer to the developing unit. The ejector ejects the image developer to an outside of the developing unit. The condition detector detects a condition of the image developer used for an image forming operation to determine a supply amount of the image developer to supply to the developing unit. The condition includes a degradation level of the image developer.

摘要： A transfer residual toner that has not been electrostatically transferred onto a transfer paper P at a transfer nip and remains on a surface of a photosensitive element is temporarily retained by an elastic blade of a toner retaining unit in a mechanical manner before reaching a latent image forming area. When passing through the latent image forming area, the transfer residual toner is returned onto the surface of the photosensitive member at such a timing that writing is not performed by an exposing unit on the surface of the photosensitive element.
