摘要:
A developer supply container supplies a developer detachably set in an image forming apparatus. The developer supply container includes a main body for containing the developer; a discharge opening, which is provided in the main body, for discharging the developer; and a plurality of feeding projections, which are disposed so as to project from a curved inner surface of the main body, for feeding the developer in the main body toward the discharge opening with rotation of the main body. Each of the projections is linear without being twisted, wherein adjacent ones of the plurality of feeding projections include portions, which overlap each other as seen in a direction of an axis of rotation of the main body.

A control device includes output means for outputting a signal for controlling an electro-optical device having a plurality of pixels which are provided so as to correspond to intersections of a plurality of scanning lines and a plurality of data lines, to the electro-optical device, and control means for controlling the output means to output a signal for applying a voltage corresponding to data stored in a memory to the plurality of data lines, whereby an image which is written by the signal when a first condition is satisfied has a higher spatial frequency of grayscale variations in an extending direction of the data lines than that of an image which is written by the signal when a second condition is satisfied.
摘要:
A control device includes a writing device that writes an image according to image data, through a plurality of frame periods, to a plurality of pixels that compose a display section, and a refresh processing device that performs refreshing a group of pixels that is subject to refreshing among the plurality of pixels when a value concerning the number of times of image writing performed by the writing device since the last refreshing is equal to or greater than a threshold value. While the refresh processing device is performing refreshing, the writing device does not perform image writing with respect to the group of pixels that is subject to the refreshing, but performs image writing with respect to a group of pixels that is not subject to the refreshing.
