Abstract: A developing device includes a developing container, first and second stirring-conveyance members, a developer carrier, a toner concentration sensor, a scraper, and a scraper attachment unit. The second stirring-conveyance member includes a rotation shaft, a first spiral blade to convey developer in an axial direction, and a second spiral blade to overlap a region where the first spiral blade is formed, which is opposite to the first spiral blade in phase, and lower than the first spiral blade in height in a radial direction. An absent region, where the second spiral blade does not exist, is formed in one pitch of the first spiral blade, the one pitch facing the toner concentration sensor. The scraper attachment unit is formed to extend, along a straight line passing through intersection points of the first and second spiral blades and parallel to the rotation shaft, into the absent region.

Abstract: An image processing apparatus converts multi-valued data into multi-valued quantized data having fewer levels than the multi-valued data. The apparatus includes an acquisition unit that acquires threshold values, a provisional quantization unit that sets a provisional quantized value with respect to the multi-valued data, and a quantization unit that decides a quantized value with respect to the multi-valued data based on a result of comparing comparative multi-valued data for the multi-valued data to the threshold value. The quantization unit decides the quantized value so that in a case where the multi-valued data is the same intermediate value, pixels having the value larger than provisional quantized value increase, pixels having the provisional quantized value do not change in number, and pixels having the value smaller than the provisional quantized value decrease in a designated pixel area as the value of the multi-valued data rises.

The recording unit includes first and second recording parts each having multiple discharge orifice rows that each have multiple discharge orifices arrayed in a predetermined direction. The first recording part and the second recording part are separated from each other in an intersecting direction that intersects the predetermined direction. The scanning unit performs recording scanning by moving the recording unit. The recording control unit performs recording of a region on the recording medium including one edge of the recording medium by the first recording part alone, recording of another region including the other edge of the recording medium by the second recording part alone, and recording of a region in between the two regions using both recording parts.

Abstract: A recording apparatus acquires residual amounts of respective tanks and determines a recording area of one recording head and a recording area of another recording head from among the two recording heads based on the acquisition result, so as to reduce a difference between residual amounts of ink within the tanks corresponding to the respective recording heads.

Abstract: The remaining amounts of inks in tanks are obtained, and, based on the obtained results, whether direction for printing an image next is to be inverted with respect to a set direction. This can reduce a difference in ink remaining amount between the tanks corresponding to print heads.

Abstract: In low-resolution processing (reduction processing) in which input image data is separated into character print data and image print data to generate print data of lower resolution than that of the input image data, if a plurality of pixels is simply reduction-processed to one pixel, color of a color image surrounding a character may change. In an image processing method, calculation for performing reduction processing so that the plurality of pixels in the input image data corresponds to one pixel in the print data is performed as follows. A ratio of using a pixel value of a character attribute pixel in the calculation is set to 0, or set smaller than a ratio of using a pixel value of an image attribute pixel. As a result, a change in the color of the color image surrounding the character can be prevented.
