Abstract: PROBLEM TO BE SOLVED: To improve reproducibility of output image by reproducing an image of high definition by carrying out density control prior to image formation when forming a specific image. SOLUTION: In this image-forming device, a density control mode is started, when a specific printing mode is instructed from pay image information, the density of a toner image formed on an image carrier is detected by a density detection executing part, and the detected result is sent to a density control setting part (S201, 202). Then, a most appropriate developing bias is calculated, and the developing bias at the time of image formation is set (S203). Here, a number (n) of frequeny that density control is carried out in the first specific printing mode is counted.  If the number of times that the density control is carried out reaches the number of times (a) (a is an arbitrary number), or if the density control result is decided as being acceptable, even when the number is smaller than the number of times a (S205, 206), whether or not there is a request for carrying out density control from a user is confirmed (207). If there is a request from the user for carrying out density control, the density control is carried out again (S202), but if there is no request, the image formation of the pay image is made to start (S208).

Abstract: PROBLEM TO BE SOLVED: To prevent deformation due to thermal expansion according to insolation without giving previous tensile force to an outer plate by forming the outer plate for a vehicle such as a bus, etc., in a cross-sectional shape curved to be protruded on the outside of a vehicle and joining an auxiliary plate of a linear expansion coefficient which is smaller than a linear expansion coefficient of this outer plate on an inner surface of the outer plate along the curved direction. SOLUTION: An outer plate 12 is installed on a car body of a bus in order to extend in the longitudinal direction of a vehicle, but in this case, the outer plate 12 is formed in a shape curved in a circular arc shape in the width direction. Thereafter, a narrow paper tablet type auxiliary plate 24 made of a material smaller in a thermal expansion cofficient than the outer plate 12 is joined on an inner surface of this outer plate 12 by adhesion by a thermosetting adhesive, etc.  Consequently, in the case when a car body part of the bus rises in temperature by insolation and the outer plate 12 expands, as the auxiliary plate 24 is joined on the inner surface of the outer plate 12, it is deformed so that a curvature becomes large by a principle of a bimetal, and as deformation is caused roughly uniformly along the overall length of the outer plate 12, it is possible to prevent irregular denting deformation.
