Abstract: A recording medium processing apparatus includes: a pressing unit that presses one surface of a transported recording medium against a to-be-pressed section; and a cutting unit that cuts the recording medium pressed against the to-be-pressed section.

Abstract: Provided is a recording material processing apparatus including: a recording material support portion configured to support a recording material loaded thereon from below; a contact member disposed on a side of the recording material loaded on the recording material support portion and configured to be pushed by an edge portion of the recording material, the contact member being configured to move to a side opposite to the side of the recording material; an elastic member configured to receive a load from the contact member pushed by the edge portion of the recording material; and a member support portion disposed without contacting the recording material loaded on the recording material support portion and configured to support the contact member.

Abstract: A recording-material processing apparatus includes a supporter, an advancing unit, and a contact member. The supporter supports at least one recording material from below. The advancing unit advances toward the recording material from a lateral side of the recording material supported by the supporter. The contact member is attached to the advancing unit and comes into contact with an edge of the recording material as the advancing unit advances toward the recording material. The contact member is movable in a direction opposite to an advancing direction of the advancing unit.

Abstract: A charging device includes a charging member that is opposed to and contacts a charged body, the charging member extending axially and rotating in response to rotation of the charged body, a cleaning member that extends axially along the charging member, and contacts a surface of the charging member to clean the charging member, a holding member that holds the charging member and the cleaning member in a manner allowing their displacement by a substantially constant amount while maintaining a distance between their axes, multiple bearing members provided to the holding member with their rotation being arrested, the bearing members individually supporting the shafts of the charging member and cleaning member in a manner allowing their rotation, the bearing members being displaced to follow a change in orientation of the shafts, and an urging member that urges the holding member to press the charging member onto the charged body.

Abstract: 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.

Abstract: 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.

Abstract: A method of preventing a decrease in sweetness of thamatin, characterized in that, chitosan or hydrolyzed chitosan is added to thaumatin in an amount which is effective for prevention of a decrease in sweetness of thaumatin.
