摘要： An image forming apparatus includes at least one image forming unit, a primary transfer belt, and a secondary transferer. The image forming unit includes an image carrier and a primary transfer bias applicator. The secondary transferer includes a secondary transfer nip, a secondary transfer bias applicator, and a facing member facing the second transfer bias applicator. The secondary transfer bias applicator forms a secondary transfer electric field. The image forming apparatus further includes a bias applicator, a contact start site, and an electrode. The bias applicator applies a bias voltage having a same polarity as the normal charge polarity of the toner to the primary transfer belt, downstream of the primary transfer bias applicator. The recording medium starts to contact the toner image at the contact start site, located upstream of the secondary transfer nip, where the electrode forms an electric field.

摘要： A steering control section has a first steering angle correction amount calculating section, a second steering angle correction amount calculating section, and a motor rotational angle calculating section. The first correction amount calculating section calculates a first correction amount based on a vehicle speed and an actual steering wheel angle. The second correction amount calculating section calculates a second correction amount through multiplying a control gain corresponding to the vehicle speed with a value calculated by low-pass filtering a differential value of steering wheel angle. The motor rotational angle calculating section calculates a motor rotational angle corresponding to the value adding the first and second steering angle correction amount, and outputs it to a motor driving section so as to drive an electric motor for correcting the steering angle. Thereby, an unstable vehicle behavior due to a resonance of a yaw motion caused in the steering operation can be suppressed.

摘要： A transfer member and a downstream-side neutralizing electrode make a contact with a rear portion of an intermediate transfer belt within a contact region. A transfer voltage with an opposite polarity to a regularly charged polarity of a toner is applied to the transfer member. A voltage with a same polarity as the regularly charged polarity of the toner is applied to the downstream-side neutralizing electrode.

摘要： An estimated value of wakefulness is calculated from the ratio between the quantity of high frequency components and the quantity of low frequency components obtained by performing frequency transformation of vehicle displacements (S51). An imaginary deviation line is set between a lane marking and the vehicle according to the estimated value of wakefulness (S55, S59, S62, S66), and an alarm is issued when the vehicle deviates from the imaginary deviation line. Since the alarm is issued when the vehicle is at a predetermined distance from the lane marking, alarming can be performed at substantially constant timing.

摘要： In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.

摘要： An image forming apparatus of the present invention includes a bias power supply for applying a bias VB to a developer carrier on which a developer is deposited. A charge potential deposited on an image carrier, which faces the developer carrier for forming a latent image thereon, is 400 V or below in absolute value. Assume that the potential of the image carrier is lowered to VL after exposure, that a development potential is |VB−VL|, that the maximum set value of the development potential for development is |VB−VL|max, and that the development potential varies in a range satisfying relations: |VB−VL|≦|VB−VL|max+|VB−VL|max×0.2 |VB−VL|≧|VB−VL|max−|VB−VL|max×0.2 |VB−VL|max≦300 V Then image density varies by a width of 10% of image density corresponding to the maximum set value of the development potential or less.
