摘要： An apparatus fixes a toner image formed on a recording medium and has a fixing roller which is rotated. The fixing roller is heated and the toner image is fixed on the recording medium being in pressed contact with said fixing roller. Offset toner particles formed on the fixing roller are decomposed into particles being too small to be perceived as a picture by an offset toner decomposing device before such large particles to be perceived as a picture are formed, and the small offset toner particles are stuck onto and removed by the recording medium. Preferably, the offset toner decomposing device is a brush roller which is rotated relative to the rotation of the fixing roller such that the brush roller and the fixing roller have equal peripheral speeds. The amount of offset toner being formed is decreased by reducing the creation of offset toner particles on the fixing roller by decreasing a torque fluctuation of a drive motor of the fixing roller.
摘要翻译：一种装置固定形成在记录介质上的调色剂图像，并具有旋转的定影辊。定影辊被加热，并且调色剂图像被固定在与所述定影辊压接的记录介质上。形成在定影辊上的偏移调色剂颗粒被分解成太小的颗粒，不能被形成为被感知为图像的大颗粒之前由偏移调色剂分解装置感知为图像，并且小的胶印调色剂颗粒被粘附到由记录介质去除。优选地，偏移调色剂分解装置是相对于定影辊的旋转而旋转的刷辊，使得刷辊和定影辊具有相等的圆周速度。通过减少定影辊的驱动电机的转矩波动来减少定影辊上的胶印调色剂颗粒的产生，从而减少形成的胶版调色剂的量。

摘要： In the continuous carburization furnace in which the temperature of the heaters can be controlled individually at every carburization processing position; carburization reference data at each carburization processing position is read; a temperature and carbon potential at each position at least during carburization and diffusion processes is detected; a carburized quantity of the processed member at each position is calculated with reference to the detected temperature and carbon potential; a carburization history is calculated by integrating the carburized quantity at each position of the carburization processed member, and a carburizing condition at a next carburization processing position is determined depending on a difference between the carburization history at the time of terminating the carburization process at each position of the carburization processed member and the carburization reference data at each position. In this way, a fluctuation of the carburizing condition based on a history of the carburization degree at each carburizing position is reduced and the productivity rate of the continuous carburization furnace is improved without stagnation of processing even upon changing a carburizing condition.

摘要： A belt-type transfer device which includes an endless belt rotating in contact with a photosensitive drum, with the belt being electrically charged by a corona discharger in a region of contact between the belt and the drum. A plate is provided for shielding the belt from the corona discharging in a vicinity of an outlet of the contact area to reduce electrostatic traction forces between the drum and the sheet in a vicinity of the outlet. The corona discharger may be located near an inlet of the region of contact with respect to a center thereof or a dielectric or electrically conductive film may be provided on an inner surface of the corona discharger on the contact area outlet side to increase the electrical charge of the belt at the inlet and the central portion of the region of contact. A control system detects an electric resistance value of the sheet and changes the corona discharging intensity in accordance with a detected value to stabilize an electrical charge of the belt or, a control system may be provided for slightly lowering a moving speed of the sheet as compared with a rotational speed of the drum at an outlet of the region of contact. Surface roughness of the belt is 5 .mu.m or less and the sheet delivery guides are provided having a volume resistivity of 10.sup.11 .OMEGA.cm or less, which reduces electrical charge caused on the sheet due to frictional contact.
