    Abstract: An image forming apparatus includes a conveying path that continues to a paper feeding unit and a paper discharge unit, a conveying mechanism that conveys a sheet along the conveying path, plural liquid ejecting heads that eject liquid onto the sheet conveyed on the conveying path, a sensor that is provided in a position between the plural liquid ejecting heads and the paper discharge unit and measures the glossiness of the sheet on which the liquid is ejected, and a control mechanism that compares the glossiness of the sheet immediately after the liquid is ejected and the glossiness measured by the sensor to calculate drying time of the liquid and controls conveying speed of the conveying mechanism to equalize conveying time for the sheet from the plural liquid ejecting heads to the paper discharge unit with the drying time.

    Abstract: An ink jet head having ink chambers, energy-generating elements provided in the ink chambers, respectively, and ink outlet ports communicating with the ink chambers, respectively. The ink jet head may be left unused for a time longer than a predetermined time, with a meniscus formed in each ink outlet port. In this case, a drive pulse is applied to each energy-generating element several times, thereby forcing the ink outwards from the ink outlet port and increasing a surface area of the ink from a surface area of the meniscus. Then, a negative pressure is applied in each ink chamber, thereby drawing the ink back toward the ink chamber, thus forming a meniscus again in the ink outlet port. In this condition, a drive pulse is applied to the energy-generating element, thus ejecting an ink droplet from the ink outlet port to record data.

    Abstract: Image data of 256 gradations is converted into that of 4 gradations which can be recorded by a recording head, at a pseudo-halftone processing unit and the converted image data is supplied to a head driving unit. A control signal selector selects a control signal A from a control signal A setting unit when the image data is a natural image, and a control signal B from a control signal B setting unit when the image data is a character or a line drawing. The head driving unit generates an electric signal used to drive the recording head on the basis of gradation information from the pseudo-halftone processing unit and the control signal A or B. With this operation, when the image data is a natural image, recording is carried out with a pixel dot for image formation excellent in gradation property, and when the image data is a character or a line drawing, recording is carried out with a pixel dot for image formation which causes no jaggy or blur to be generated at hatched portions and the like.

    Abstract translation: 256个灰度的图像数据被转换为可由记录头在伪半色调处理单元记录的4个灰度的图像数据，并将经转换的图像数据提供给头驱动单元。 当图像数据是自然图像时，控制信号选择器从控制信号A设置单元选择控制信号A，以及当图像数据是字符或线条图时来自控制信号B设置单元的控制信号B. 头驱动单元根据来自伪半色调处理单元和控制信号A或B的灰度信息产生用于驱动记录头的电信号。通过该操作，当图像数据是自然图像时，记录是 进行具有优异的灰度特性的图像形成的像素点，并且当图像数据是字符或线条画时，利用图像形成的像素点进行记录，从而在阴影部分不产生锯齿或模糊 等等。
