    摘要: The image forming apparatus of the invention controls the toner density by any one of the following configurations: by prohibiting toner supply for a constant duration to prevent excessive toner supply if time from the end of the last operation of the developing unit to the start of a next operation, inclusive of the power-activation is equal to or longer than a predetermined period when the developing unit is activated to commence agitation of the developer; by correcting the toner density of the developer in association with the agitation total; by controlling a process parameter so that the density of a toner patch formed on the photoreceptor corresponds to a prescribed density value and determining that developing performance of the developer is improved and canceling the toner density correction when the process parameter reaches the prescribed value; or by changing the toner density reference value when the variation as to the charger output is equal to or greater than a first predetermined value and maintaining the changed toner density reference value until the variation of the charger output again becomes equal to or greater than the first predetermined value.

    摘要: An image forming apparatus is provided with a photoreceptor drum (31) which includes a barrel-shaped drum whose surface is coated with a photosensitive layer, and a rear-side drum flange section; and a developer. A coupling section at which the photoreceptor drum is attached to or detached from an image forming apparatus main body includes an input section and an apparatus output section. The input section is composed of an internal gear (36) having teeth of an involute curve formed in an inner surface of the rear-side flange section and receives rotation driving force from the image forming apparatus main body. The apparatus output section is composed of an external gear (67) having teeth in the same shape and in the number as the internal gear, and outputs the rotation driving force from the image forming apparatus main body to the input section.

    摘要: A process control apparatus of electrophotographic apparatus has an optical sensor (16) for optically detecting the density of toner patches formed on a photoreceptor drum (1). The present apparatus is further provided with a control device for controlling lamps (4) for the copying process, chargers (7) and other elements. A toner patch is formed on the photoreceptor (1) so as to be located between every two toner images for a copying operation. The control device controls the lamps (4), chargers (7) and other elements in accordance with the result of the toner patches detected by the optical sensor (16) so as to stabilize the copying picture quality. With the arrangement, it is avoided that the job efficiency during the copying operation deteriorates, and the control data obtained from the toner patches is soon used for the toner image formation for the copying operation, thereby ensuring that the process control improves in accuracy.
    Additionally there is disclosed a control method based upon the change of temperature within or in the vicinity of the apparatus.

    Additionally there is disclosed a control method for controling background developing.
