摘要： During a first rotation of a photoconductor, latent electrostatic images for color correction processing patterns are formed on the photoconductor, and the latent electrostatic images are developed into the color correction processing patterns in each of four colors, and then densities of the patterns on the photoconductor are detected. During a second rotation of the photoconductor, each color of the patterns is recovered back into a developer device.

摘要： A tandem color laser printer 1 is provided with a photosensitive drum unit 15, a developing unit 14, and a scanning unit 13 for each color. The developing units 14, each including a main developer unit 25 and a toner hopper 24, and the scanning units 13, which irradiate laser beam, are alternately stacked vertically to overlap with each other in the vertical direction. This arrangement eliminates space required when arranging the developing units 14 and scanning units 13 side by side, thereby reducing the footprint of the color laser printer 1.

摘要： An image forming device includes a housing, a photosensitive drum, a developing unit, and a developing-agent moving configuration. The developing unit is freely detachably attached to the housing and includes an exchangeable toner box and a developing chamber, which are freely detachably attached to each other. The toner box has a through hole for supplying toner to the developing chamber. The developing portion includes a developing roller that rotates to transport toner from the toner box to a latent image on the photosensitive drum. The developing-agent moving configuration functions to move residual toner from the developing chamber into the present toner box before the toner box is exchanged for a new toner box.

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.
