    摘要： An image forming apparatus having an intermediate guide device which is disposed at an intermediate portion between a transfer section and a fixing section for the purpose of guiding a transfer medium while imparting breadthwise tension thereto. This intermediate guide device prevents any wrinkle occurring in the transfer medium near the fixing section from being moved toward the transfer section. In addition, the toner on the transfer medium is prevented from being transferred onto upper-surface rollers of the guide device when the electric charge of the toner leaks to the rollers.

    摘要： An ink jet printing apparatus for industrial use, which is provided with a comparatively large number of nozzles arranged for high duty recording, particularly an ink jet textile printing apparatus, and an ink jet printing apparatus suitably used for printing on a large-sized medium, are provided together with a method for controlling the temperature of the printing head of such high duty printing apparatuses, and various other types of printing apparatuses reliably. To the large number of heaters used for recording in a printing step, driving signals are applied to cause them to discharge ink for recording and, to the discharge heaters that are not to perform recording, secondary driving signals that do not allow ink to discharge are applied. These secondary driving signals cause the heaters not used in recording to generate heat, so as to reduce unevenness in the intensities of heat generation among the many discharge heaters of the printing head. At the same time, cooling water is supplied by a cooling device to a cooling liquid path arranged for the printing head in order to cool it.

    摘要： An image forming apparatus includes conveying device for conveying a printing medium in the substantially horizontal direction in the printing range where a printing agent is applied to the printing medium while a printing plane of the printing medium orients in the upward direction, a printer section including a plurality of printing heads located opposite to a platen portion of the printing range for applying the printing agent to the printing medium in the downward direction so as to form printed images on the printing medium by activating the printing heads, and supporting device for slidably displacing the printer section relative to the platen portion in the conveying direction of the printing medium conveyed by the conveying device, between the position where the printer section is located opposite to the platen portion and the non-opposing position spaced away from the preceding position. With such construction, a maintenance service can easily be conducted for the conveying device.
