    摘要: A transfer device includes an endless member caused to circulate by a driving unit, plural transfer members coming in contact with a rear surface of the endless member and transferring toner images on image holding members to the endless member, a support member movably supporting a specific transfer member of the transfer members located at a position which is more upstream in a circulation direction of the endless member than a contact position where a recording medium comes in contact with the endless member and which is closest to the contact position, a regulation member regulating the movement of the specific transfer member in a state where the specific transfer member is disposed at a position where the toner image formed on the corresponding image holding member is transferred to the endless member, and a first impelling member impelling the support member to the regulation member.

    摘要: In an on-demand ink jet printer head for discharging minute ink drops by means of meniscus position control and acoustic wave control, the length of each discharge pause period with respect to each orifice of the printer head is determined based on image data, and a pre-discharge waveform is determined for each discharge pause period based on the length of the discharge pause period. The pre-discharge waveform is applied to a piezoelectric element before restart of ink drop discharge by the movement of the piezoelectric element, thereby a large displacement which is designed depending on the length of the discharge pause period is given to ink before the restart of the ink drop discharge so that the ink will be moved and stirred, thereby uniformity and stability of ink drop discharge properties (size, speed, flying direction, etc.) are realized at the restart after the discharge pause period. Continuous meniscus vibration is not employed for maintaining ink viscosity during the discharge period.
