摘要： A latent image formed on a photosensitive member in exposure operations is developed into a toner image, which is then transferred onto an image bearing member in primary transfer operations. Afterward, the toner image is transferred onto a recording sheet in secondary transfer operations. A cleaning unit for cleaning the image bearing member by removing residual toner therefrom is brought into and out of contact with the surface of the image bearing member at a time when neither the exposure operations nor primary transfer operations are being performed.

摘要： A piezoelectric body formed onto one surface of an insulation sheet of an aperture electrode, the piezoelectric body being in direct confrontation with a toner-bearing roller. The piezoelectric body is formed of a mixture of a binder and piezoelectric material particles provided by pulverizing a piezoelectric material mass. A plurality of apertures are formed through the insulation sheet and the piezoelectric body, and control electrodes are provided around each aperture. The piezoelectric body is deformable upon generation of an electrical field. In a first deformation of the piezoelectric body, the thickness of the piezoelectric body is increased to provide a dam at a downstream portion of the aperture, which facilitate the toner orientation toward the aperture.

摘要： In a developing device for an image forming device, such as a laser printer, a supply roller is in rolling contact with and supplies toner particles to a developing roller which in turn is in rolling contact with a photosensitive drum and supplies toner particles to an electrostatic latent image formed thereon. The developing roller and the supply roller press against each other with a slight pressure. The supply roller has a resilient outer form layer formed from a silicone foam or urethane foam and fluororesin particles are dispersed within the foam. With the dispersion of the fluororesin particles throughout the resilient outer form layer of the supply roller, toner particles can be better charged by contact between the resilient outer foam layers of the supply roller and the developing roller. As a result, improper image development is less likely to occur and the developing roller will not scratched or otherwise damaged.

摘要： An image recording apparatus using a set of mask members and having mask position adjusting device. A transparent mask member supporting plate is provided at the exposure position. Each of the mask member is delivered upon the mask member supporting plate by two pairs of rollers. In this mask delivery, a mask image surface faces upwardly. An elongated photosensitive recording medium is positioned immediately above the mask member supporting plate so as to guide the medium at the exposure position. Further, an exposure device including a light source and color filters is positioned below the mask member supporting plate. The mask member undergoes positional adjustment at the exposure position. For this, the mask member supporting plate is supported on a positioning frame which is movable in a direction perpendicular to the mask member moving direction. The position of the mask member with respect to the running direction thereof is controllable by controlling rotations of two pairs of rollers, and the mask position with respect to its tranverse direction is controllable by controlling the movement of the positioning frame.
