摘要： An electrostatic latent image is formed on a rotary image carrier. A developing roller is separatably abutted on the image carrier to supply toner onto the image carrier to make the latent image visible as a toner image. An intermediate transfer member is adapted to temporarily hold the toner image. A first transferer presses the intermediate transfer member against the image carrier to define a primary transfer position therebetween, so that the toner image on the image carrier is transferred to the intermediate transfer member. A second transferer is separatably abutted on the intermediate transfer member to transfer the toner image on the intermediate transfer member to a recording medium. An operation for forming the latent image is started after a predetermined time period elapses since a toner attached on at least one of a first region of the intermediate transfer member, on which a toner image to be transferred onto the recording medium is not transferred, and a second region on the image carrier corresponding to the first region has passed through the primary transfer position.

摘要： A CPU 113 executes a control program stored in a memory 116 thereby forming a plurality of patch images with a developing bias increased for each of the patch images; detecting a density of each of the patch images by means of a patch sensor 17; and comparing the image densities to determine whether the image density is saturated or not. Then, an image forming condition in which an image density is substantially saturated is determined and is stored in the memory 116. When a print command signal is inputted from an external device via a main controller 100, a printing operation is performed under the image forming condition stored in the memory 116.

摘要： A CPU 113 executes a control program stored in a memory 116, whereby a patch image is formed on a photosensitive member of a photosensitive member unit 10, a light emitter 171 irradiates light upon the patch image, a light receiver 172 receives light from the patch image, whether a received-light signal from the light receiver 172 is within a tolerable range is determined, and an image forming condition is controlled and stored in the memory 116 when the received-light signal is outside the tolerable range. Upon entry of a print instruction signal from an external apparatus via a main controller 100, a printing operation is executed under the image forming condition stored in the memory 116.
