In order to provide a driving mechanism for a photosensitive drum which is capable of reducing deformation of the shaft of the photosensitive drum caused by loads when transmitting a driving force, a drive transmission course 51 is diverged to at least two courses in a drive transmission system 42 for transmitting the drive force from a drive motor 41 to the photosensitive drum 25. Specifically, the last stage of the drive transmission course 51 is engaged with a passive member 47 provided to the drum shaft 25a at two or more points to connect and link the drive force, thereby diverging the directions of loads to several directions, by which irregular movements of the photosensitive drum or vibration caused by the deformation of the shaft is eliminated.

Image forming apparatus and driving mechanism for image holding member

A magnetic roller is fixedly mounted in a developing device provided in an image forming apparatus. The magnetic roller includes a magnetic member, which is made of a mixture of ferromagnetic material and polymeric compound. A plurality of magnetic poles are formed along the periphery of the magnetic member and consist of a main magnetic pole confronting an electrostatic latent image support member of the image forming apparatus, at least two magnetic poles formed adjacent to each other on one side of the main magnetic pole and having a polarity opposite to the polarity of the main magnetic pole, and at least two magnetic poles formed adjacent to each other on the other side of the main magnetic pole and having a polarity opposite to the polarity of the main magnetic pole.

There is disclosed a corona discharger comprising a discharge wire for producing a corona discharge, a voltage source for applying a predetermined voltage to the discharge wire, an electrically conductive back plate being provided on the opposite side of the discharge wire to a member to be electrified, and an electrically conductive side plate being provided close to the member to be electrified. In the corona discharger, an opening for discharging ozone produced by said corona discharge is formed between said side plate and said back plate, and respective electric potentials of the side plate and the back plate are set so that a difference between respective electric potentials of the side plate and the discharge wire becomes lower than a difference between respective electric potentials of the back plate and the discharge wire.

An air conditioning system for buildings includes a plurality of air conditioners on the different floors, a cooling gravity type heat pipe connecting vaporizers in the air conditioners with a cold thermal source installed at the top of the building and a warming gravity type heat pipe connecting a condenser of the air conditioners with a hot thermal source installed in the basement of the building. The heat pipes are, respectively, provided with flow control valves at the inlet of each vaporizer and the outlet of each condenser. Each air conditioner is provided with a thermistor for detecting the temperature of the returning air and a liquid level detection switch for detecting the liquid level of the thermal medium in the vaporizer. The flow control valves are respectively controlled based on the detection signals issued by the thermistor and the liquid level detection switch.

Air conditioning system for buildings

An air conditioning system for a building according to the present invention essentially has a first thermal storage tank as a cold thermal source which is installed at a high place in the building, a second thermal storage tank as a hot thermal source which is installed at a low place in the building, air conditioners which are installed at various levels between the first thermal storage tank and the second thermal storage tank, and heat pipes of a gravity type with which the air conditioners are connected to the first thermal storage tank and the second thermal storage tank. This system dispenses with passages for water, typically used as a thermal medium, at the places where air conditioners are installed. The system makes it possible to lower the capacities of the air conditioning equipment, especially the capacity of the regrigerator included in the cold thermal source equipment.
