Abstract: An image forming apparatus includes: an image carrier configured to carry a toner image; a transfer member configured to transfer the toner image onto a transfer target member by applying a transfer voltage of the opposite polarity of the polarity of the toner image to the transfer target member, the transfer member being in contact with the image carrier; an accepting unit configured to accept a setting for changing a preset current range to a new current range, the preset current range being defined by one of a lower limit of a current flowing in the transfer target member and an upper limit of the current; a sensing unit configured to sense a magnitude of the current flowing in the transfer target member; and a control device configured to control the transfer voltage so that the magnitude of the sensed current falls within the new current range.

Abstract: A posture of a component is to be accurately determined.
A posture determination method is to determine, based on an image acquired for a component having a plurality of surfaces, a posture of the component. This posture determination method includes recognizing an outer shape of the component from the image, detecting a feature amount of a surface shape in a determination area being a part of the component based on the outer shape of the component recognized in the recognizing, and determining. In the determining, the posture of the component is determined by comparing a first reference amount indicating a reference feature amount in the determination area of a first surface of the component and a second reference amount indicating a reference feature amount in the determination area of a second surface of the component with the feature amount detected in the detecting.
