摘要： A high density detecting toner pattern is formed on a photosensitive body and a high density correction is effected by comparing a value detected by a reflection sensor with a high density reference value so as to maintain an image density at a specific level. An image density correcting section adopts a result of the preceding high density correction as the high density reference value, and compares the same with a result of a current high density correction. The image density correcting section effects the half-tone density correction only when a difference reaches or exceeds a preset difference reference value by forming a half-tone density detecting toner pattern on the photosensitive body and comparing a value detected by the reflection sensor with a half-tone reference value. Consequently, it has become possible to provide an image forming apparatus which can maintain a density output of an entire image at a specific level for any kind of images including solid, line, and half-tone, etc. while shortening a time required for the density correction and reducing a quantity of toner consumed for the density correction.
摘要翻译：在感光体上形成高密度检测调色剂图案，并且通过将由反射传感器检测的值与高密度参考值进行比较来实现高密度校正，以将图像浓度保持在特定水平。图像浓度校正部分采用先前的高浓度校正的结果作为高密度参考值，并将其与当前高密度校正的结果进行比较。图像浓度校正部仅通过在感光体上形成半色调浓度检测调色剂图案而将差分达到或超过预设差值基准值来实现半色调浓度校正，并将反射传感器检测到的值与半参考值。因此，可以提供一种图像形成装置，其可以将包括实线，线条和半色调等的任何种类的图像的整个图像的浓度输出保持在特定的水平，同时缩短所需的时间密度校正和减少密度校正所消耗的调色剂量。

摘要： An object of the present invention is to obtain, in an accurate and stable manner, an image density at a tone rise point in a low-density region in order to form a stable image. At the time of execution of an image density correction in an image forming apparatus which employs an electrophotographic process, a toner pattern of a plurality of toner patches is formed on the basis of a reference density correction table which specifies an image density output value used for correction of an image density input value, the density of the toner patches is detected by a density detecting sensor, points corresponding to a plurality of image densities in a low-density region, detected above a predetermined level of sensitivity of the sensor, are plotted thereby to find a linear interpolation formula, an image density in the low-density region below the predetermined level of sensitivity of the density detecting sensor is interpolated with the linear interpolation formula, a comparison between the reference density correction table and a result of the interpolation is made so as to correct the image density output value, and a correction table as a post-modification correction table is prepared. An actual image is prepared using the correction table.

摘要： A developing device having a reduced size in the horizontal direction and in which a developing agent is transported with stirring along a circulating route inside a developing tank to effectively mix newly added toner therewith and stir the mixture. A developing tank for storing developing agent therein is horizontally divided with a partition member thereby providing an upper chamber and a lower chamber. A developer roller and a stirring roller are disposed in the lower chamber. Two screw rollers are disposed in the upper chamber. An inlet opening is formed between an end of the partition member and a regulating member for restricting a layer if the developing agent adsorbed to the developing roller. A developing agent removed by the restricting member is fed through an inlet opening to the screw rollers in the upper chamber. The developing agent is mixed with fresh toner supplied through a supply inlet and transported with being stirred by the screw roller in its axial direction. Then, the developing agent is transferred to the screw roller disposed parallel to the screw roller and it is further transported and returned to the stirring roller in the lower chamber through a return port provided opposite to the screw roller. The compact construction of the developing device is realized by arranging screw rollers for stirring and transporting toner in the upper chamber.

摘要： A mirror converging-type illumination optical system for converging light rays from a light source into substantially parallel light rays using a concave reflecting mirror having a secondary curved surface comprises a conical refraction member having a convex conical refraction surface at an input or incident side thereof and another convex conical refraction surface at an output side thereof. The refraction member is arranged in a path of the parallel light rays with a vertex of the conical refraction member being substantially aligned with the optical axis of the illumination optical system. The refraction member inverts the inner and outer portions of the incident parallel light rays. The absence of incident parallel light around the optical axis thereof is corrected to achieve a uniform intensity of light rays.

摘要： A projection type exposure apparatus has a projection objective lens, a projection negative having a predetermined shape pattern and an alignment mark, and a photosensitive plate having an alignment mark. The shape pattern of the projection negative is projected upon the photosensitive plate by the projection objective lens. Main illuminating optical means illuminates the projection negative with a first wavelength light to which the photosensitive plate is sensitive, and alignment optical means illuminates the projection negative with a second wavelength light to which the photosensitive plate is insensitive. The positional relation between the projection negative and the photosensitive plate is detected using the second wavelength light through the projection objective lens. One of the alignment mark on the projection negative and the alignment mark on the photosensitive plate has a zone pattern which forms a light-condensing point at a position spaced apart by a predetermined amount from the surface on which said one mark is formed, and said predetermined amount corresponds to the amount of chromatic aberration of the projection objective lens, at the side thereof adjacent to said zone pattern, for the second wavelength light relative to the first wavelength light.
