An end of toner detector to be utilized in a toner cartridge of a developing apparatus of an image forming apparatus. A developing device develops latent images formed on an image bearing member so as to form toner images. A toner storage unit deposits toner to supply to the developing device. A light path forming unit protrudes from a wall of the toner storage unit into an interior of the toner storage unit and forms the light path through which light passes in the toner storage unit. A light sensor includes a light emitting unit which emits light and a light receiving unit which receives light emitted from the light emitting unit. Further, the light sensor outputs signals which smoothly change according to an amount of toner in the light path formed in the light forming unit.

In a device cover fastened to a casing of a vibration generating source to cover a device mounted on an outer surface of the casing, an elastic member having a natural frequency different from that of the device cover, is mounted in a mounting bore provided in the device cover which is fastened directly to the casing to close the mounting bore. Thus, the strength and durability requirements of the device cover are satisfied and moreover, the vibration of the device cover can be inhibited to reduce the resonance sound from the device cover in a simple arrangement.

An electrical connection box has electronic components mounted therein and includes a heat pipe for radiating heat generated from the electronic components to the outside. The heat pipe has a heat absorbing portion inside the connection box and a heat radiating portion outside the connection box. The heat pipe is formed of an electrically conductive material, and an electrically conductive heat collecting member is provided for collecting the heat generated from the electronic components. The heat absorbing portion of the heat pipe is connected to the heat collecting member, and a grounding current is supplied to the heat pipe and the heat collecting member.
摘要:
A toner density control method senses the concentration of a toner image for control formed on a photoconductive element by an optical sensor and, based on the output of the sensor, corrects a target target toner concentration for toner supplement control to be effected in response to an output of a toner concentration sensor mounted on a developing device. When the output Vs of the optical sensor is determined to be greater than a reference value Vs.sub.0 (short toner deposition), the reference value Vt.sub.0 is corrected to smaller one. When Vs determined to be smaller than Vs.sub.0 (excessive toner deposition), Vt.sub.0 is corrected to greater one. In each of such cases, a predetermined amount n.multidot..DELTA.VT is subtracted from or added to the output Vt of the toner concentration sensor of that instant.
摘要:
A toner end detecting method for an electrophotographic copier which allows the copier to operate even when a toner end condition is detected by accident or when a developing device included in the copier and being used is replaced with another storing a toner of the same color while a toner end condition is not reached. When the power source of the copier is turned off and then on or when the developing device is set on the copier, the method executes a recovery procedure.
