摘要:
The developing apparatus of the present invention is a developing apparatus that develops an electrostatic latent image using a two-component developer containing a toner and a carrier; wherein the developing apparatus has a developing roller that rotates with a developer adhering to the peripheral surface thereof in order to transfer the developer to an electrostatic latent image; a bias unit having a DC voltage applicator that applies a prescribed DC voltage to the developing roller and an AC voltage applicator that applies an AC voltage to the developing roller; a timer that measures the developing apparatus drive time; a measuring unit that measures the amount of developing performed by the developing apparatus; and a bias adjustor whereby the amplitude component of the AC voltage applied by the AC voltage applicator is lowered based on an increase in output of the timer and/or the measuring unit.

An image forming device includes an assignment unit that detects a size of a document image to be printed in each page for each one of a plurality of pages assigned to a plurality of print sheets that configure a booklet and, in a case where it is determined that a second document image larger than a first document image is present, assigns a page that includes the second document image to a face of a print sheet that is positioned on an outermost face or an innermost face of the booklet as an exception page and a print image generating unit that generates print images by sorting the plurality of pages that include the exception page assigned by the assignment unit.
摘要:
In a blood pressure measurement device, a force acts on one end side and the other end side of a cuff main body in a direction where an inner diameter of a tubular form is further reduced, so that a rotation shaft rotates in a clockwise direction thus simultaneously moving the one end side and the other end side of the cuff main body. As a result, the inner diameter of the tubular form of the cuff main body can be reduced, and the cuff main body can be easily and rapidly wrapped around the upper arm with only the pushing task using one hand. Thus, the blood pressure measurement device provides a simple device configuration that enables the cuff to be easily wrapped around the measurement target site even for those with crippled hands.
