    Abstract: A toner density control method applicable after detection of a toner empty condition. After each copying operation, in copying machines, a simulated original is exposed to produce a corresponding electrostatic latent image, which image is developed periodically to provide a toner image for detection of the toner image density. If a toner empty condition is detected, a toner density level lower than normal is compared with the detected toner density and then the normal toner density level is compared with the detected level. A toner density control device for forming copies having different colors is likewise disclosed. The optimum density data for development are preset according to the color of the toner contained in the developing device. Electrostatic latent images are developed and compared with the detected density level of the toner image so that a relative decrease in toner image density can be compensated by driving the toner supply device.

    Abstract: A reversible auto document feeder having a document feeding mechanism for feeding a document to a document placing position of an image forming apparatus, reversing the document, feeding the reversed document to the document placing position again, discharging the document. In order that, when attached to image forming apparatus (41) capable of sending only an ADF (auto document feed) signal, RADF (reversible auto document feed) operation can be performed, the feeder has change means (43) for changing to a forced control mode of controlling the document feeding mechanism so as to feed a document to the document placing position, reversing the document after copying, feeding the reversed document to the document placing position again, and discharging the document after copying in accordance with an ADF signal from the image forming apparatus (41).

    Abstract: PURPOSE:To insert and take out a binder into and from an insertion chamber easily and keep the binder being fixed assuredly during binding processing. CONSTITUTION:In a binding device (A), papers are adhered to an inner face of a spine cover of a binder to be inserted in an insertion chamber 12 pinching a plurality of sheets of papers for binding. In the insertion chamber 12 of the binding device (A), a binder pinching body 13 is housed movably up and down. The binder pinching body 13 is deformed to a shape for pinching the binder by a guide of the insertion chamber 12 in a state inserted until a lower part of the insertion chamber. The binder pinching body 13 is made to descend by an operating member 20 until a binding processing position where the binder sinks in the insertion chamber 12 entirely. By operations of returning means 15 and 22 which respond to an completion of the binding processing, the binder pinching body 13 is elevated to the original position where a part of the binder protrudes out of the insertion chamber 12.
