There is provided a photoreceptor cleanerless image forming apparatus capable of decreasing color mixture or an exposure error due to reverse transfer toner or untransferred toner. An image forming apparatus 100 according to the present invention comprises four image forming units 100a, 100b, 100c, and 100d configured to be photoreceptor cleanerless in a 4-drum tandem manner. Each image forming unit includes a photoreceptor 103a, 103b, 103c, or 103d, a charger 105a, 105b, 105c, or 105d, an exposure apparatus 106a, 106b, 106c, or 106d, and a developing apparatus 109a, 109b, 109c, or 109d. When exposure intensities Iy, Ic, Im, and Ik are assumed for exposure sources of the exposure apparatuses in the image forming units which form yellow, magenta, cyan, and black images, respectively, the exposure intensities are configured to satisfy conditions of Ik≧Ic≧Im≧Iy and Ik >Iy. This decreases an exposure error (image hysteresis) in an image formed on paper.

In a flexible transfer body employing curable resin as a transfer material, thickness unevenness in a substrate and a transfer layer is reduced and the thickness of the transfer layer is made to be uniform. Liquid curable resin is coated onto a rotation center or the vicinity of the rotation center of a mold, which is a rotator having a functional form on a surface thereof. A flexible film is brought into contact with a surface of the coated curable resin in a liquid state and the curable resin is spread to the circumferential edge of the mold by a centrifugal force. And the curable resin is cured by supplying chemical or thermal energy thereto and the curable resin is separated from the mold, thereby obtaining a flexible transfer body in which the curable resin is transferred to the film.

A seat air conditioner for a vehicle seat includes a blower unit which has a blower fan and an air discharge duct, a vibration isolation unit arranged between the blower unit and a cushion member of the seat, and an accordion duct which is arranged between the air discharge duct and an air passage defined in the cushion member. The blower unit is disposed at an opposite side to the cushion member with respect to seat spring members of the seat. Air blown by the blower fan flows toward a plurality of blowing-out openings formed at a surface cover member of the seat, through the air discharge duct, the accordion duct and the air passage formed in the cushion member.

摘要:
An air conditioning apparatus preferentially ventilates a space close to a seat and/or a steering wheel on which a passenger directly makes a contact in a passenger compartment while a vehicle is parked. The uncomfortable feeling of a passenger that might occur when he/she is getting into the parked vehicle can be reduced using a small capacity in the air conditioning as compared to the air conditioning apparatus ventilating the whole space in the vehicle.
摘要:
In a transfer unit of an image forming apparatus, an auxiliary transfer roller and a main transfer roller are provided relative to a photosensitive drum, with a transfer belt interposed. A low voltage for avoiding occurrence of a high electric field is applied to the auxiliary transfer roller, while a high transfer voltage for realizing sufficient transfer is applied to the main transfer roller.

A seat air conditioning unit includes a seat defining an air passage therein through which air flows toward a seat surface, and first and second blower units for blowing air in the air passage. The first blower unit is provided in a seat bottom of the seat and the second blower unit is provided in a backrest of the seat. The first blower unit includes one of a centrifugal fan, a mixed flow fan, and a regeneration fan. The second blower unit includes an axial flow fan.
摘要:
A vehicle air conditioner controls the air-conditioning automatically based on sensors detecting environmental conditions regarding the air-conditioning of a vehicle and based on an operational portion operable by a passenger. One of the sensors is a sunlight sensor for detecting the amount of sunlight incident into the vehicle. A signal detected by the sunlight sensor is modified to have a time constant by a time constant process. The modification is based on the elevation angle of the sunlight and the inside air temperature of the vehicle. The modified signal is used for automatic control of the air-conditioning.
