    摘要： An image forming apparatus wherein the copying operation is performed not only in an automatic density specifying mode but also in a manual density specifying mode according to select by an operator. When the ratio of the frequency of select of the manual density specifying mode to the frequency of select of the automatic density specifying mode has exceeded a predetermined value, the image forming apparatus is adapted to execute an image adjustment process by detecting the state of components, for example, charge wires for the purpose of adjusting the density of copy images formed in the automatic density specifying mode.

    摘要： An electrophotographic copying machine adapted to provide a copied image for preparing a master plate for a thermal type stencil printing machine as well as a copied image for other, ordinary use. The copying machine includes an image forming device including a photosensitive member defining a photoconductive layer on a surface thereof, a charging device for charging the surface of the photosensitive member, an exposure device for illuminating an original image and forming on the photosensitive member an electrostatic latent image corresponding to the original image, and a developing device for causing a charged toner to electrostatically and selectively adhere to the electrostatic latent image on the photosensitive member. The copying machine further includes a transfer device for transferring the charged toner from the photosensitive member to copying paper, and an image density dropping device for selectively controlling the image forming device to cause a sharp drop in an image density on the copying paper with respect to a density of the original.

    摘要： In a rotary type image developing apparatus that has a rotary rack accommodating a plurality of developer units and drives the rotary rack to rotate in a predetermined rotational direction so as to bring a targeted one of the developer units to a developing position, each developer unit includes a toner storage in which a first slope is disposed. As the rotary rack rotates, toner that remains upstream of a toner supply opening in a toner flowing direction in the toner storage is guided by a slope surface of the first slope, which enables the toner to be smoothly supplied to a developing chamber. Thus, even when the toner gets low, the toner can be efficiently supplied from the toner storage to the developing chamber with the aid of the first slope.
