摘要： A control system for an image forming device includes a sensor mounted on an optical path unobstructed by elements that are subject to wear for detecting a time varying signal representing reflected light from both a photoconductive element and a transfer sheet internal to the image forming device, a memory storing reference values, and a controller to control an image forming operation based on the reference values stored in the memory and the time-varying signal received from the sensor. The controller reads the time-varying signal from the sensor and compares the time-varying signal read to the reference values to determine a condition of the image forming device.

摘要： An image forming apparatus includes an image carrier and a developing device to develop a latent image formed on the image carrier by applying two-component developer, including toner, onto the latent image. The developing device includes a developing part containing the two-component developer and a developer stirring device to stir the two-component developer. A toner supplying device supplies toner to the developing part of the developing device, and a toner density detection device detects a toner density of the two-component developer in the developing device. A toner control device calculates a difference between an output value VT of the toner density detection device and a criterion value VTref for controlling the toner density of the two-component developer and controls the toner supplying device based upon the difference. An image density detection device detects an image density of a criterion image formed on the image carrier, and a criterion value correcting device corrects the criterion value VTref based upon an output value of the criterion image density detection device. A decision as to whether to stir the developer in the developing device with the developer stirring device is made based upon a difference between the criterion value VTref and the output value VT from the toner density detection device and an output value of the criterion image density detection device when an image forming operation is started.

摘要： An electrophotographic image forming apparatus is disclosed which is provided within a cleaning device with a rotative conveying member for conveying a residual toner after removal thereof from a photoreceptor up to an inlet of a toner dropping path while rotating. Within the toner dropping path is disposed a toner bridge preventing member for preventing the formation of a toner bridge in the same path. The toner bridge preventing member is driven by the rotative conveying member so as to reciprocate substantially in parallel with the toner dropping direction.
