摘要： An image forming apparatus includes a process including at least a developing section and an image bearing body. A calculating section calculates a number of the dots formed on the image bearing body. A rotation calculating section calculates a number of rotations of the image bearing body for forming the number of dots on the image bearing body in accordance with the print data. A controller makes a decision to determine whether the number of dots formed on the image bearing body is larger than a first reference when the number of rotations is larger than a second reference. If the answer is YES, then the controller forms a developer image formed of dots equivalent to a difference between the first reference and the number of dots. Then, the developer image is discarded.

摘要： A developing roller supplies toner to an image on an image bearing body, the image being formed in accordance with image data. A toner supplying member supplies developer material to the developer bearing member. A computing section computes a dot population density in corresponding one of a plurality of sub data areas. The plurality of sub data areas are obtained by dividing the image data such that the plurality of sub data areas are aligned in a printable area of a print medium in a direction perpendicular to the direction of travel of the print medium. A controller performs a developer material removing process based on the dot population density, in which the toner deposited on the developing roller is removed from the developing roller in an area corresponding to a low dot population density of image data.

摘要： A fixing device capable of improving printing speed without increasingly the size of rollers, and making the surface temperature of the heating roller quickly reach a target temperature. The heating roller, which comes into contact with recording sheet having unfixed toner adhering to it, includes an elastic body of low heat conductivity and high heat resistance, and has metal foil formed tightly to the external circumferential surface thereof. This meal foil with a small heat capacity, by direct contact on its surface with the heating source, helps the surface of the heating roller quickly rise in temperature.

摘要： A method for cleaning an image-forming apparatus. Toner is charged to the first polarity prior to transferring the toner image to the print medium and accidentally inverted from the first polarity to a second polarity opposite to the first polarity during the transfer of the toner image to the print medium. When performing a cleaning operation, a first voltage of a first polarity is applied to at least one of a charging roller and a cleaning roller in contact with a surface of a photoconductor. The surface of the photoconductor is charged to a second voltage. The second voltage has a smaller value than the first voltage and is of the same polarity as the first voltage. Therefore, the toner of the second polarity sandwiched between the charged surface of the photoconductor and the at least one of the charging roller and cleaning roller is inverted in polarity, i.e., from the second polarity to the first polarity by triboelectric charging. If the first voltage is applied to the cleaning roller, the photoconductor may be charged to the second voltage by a transfer device or by a charging device. Alternatively, if the first voltage is applied to the charging roller, the photoconductor may be charged to the second voltage by a cleaning device or by the transfer device.

摘要： An image forming apparatus in which a toner layer is formed onto a developing roller which is restricted by a toner restricting member and rotated, toner is supplied to a photosensitive drum by the toner layer, and a toner image is formed onto the drum and transferred onto a print medium, thereby forming an image. The apparatus has: a counter which counts the toner image, on a dot unit basis, formed on the drum and a control unit which stops the rotation of the developing roller for a predetermined time and intermittently executes a series of image forming operation when a count value is equal to or larger than a predetermined reference value. The occurrence of filming is prevented by preventing an increase in toner temperature.
