    • An improved printed circuit board connection for connecting a first printed circuit board to a second printed circuit board in a manner that permits physical engagement at a different position than the electrical engagement, and a method for making the improved printed circuit board connection with precision in alignment. In one embodiment, the first printed circuit board includes an end portion configured to engage with a member of a connector on the second printed circuit board. The end portion and the member engage along concave portions of the end portion and convex portions of the member. When engaged, the end portion and the member align wires of the first printed circuit board with terminals of the connector.

    • Image forming apparatus which form an image on a substrate and uses a liquid developer containing toner particles and a solvent. One embodiment includes a latent image retaining body, a first developing surface facing the latent image retaining body at a first development station, a latent image forming unit, and a second developing surface facing the latent image retaining body at a second development station. The latent image retaining body has a photosensitive layer which has a dielectric constant nullp nullC2/Nm2null and an average thickness dp nullmnull. The photosensitive layer retains an image developed by the first developing surface and a latent image comprising image and non-image regions formed by the latent image forming unit. The second developing surface is supplied with a developing electrical potential having an electrical potential difference nullV from an electrical potential of non-image region of the latent image. The plurality of toner particles of the first liquid developer has a volume density nullm nullkg/m3null, a surface density mr nullkg/m2null, a dielectric constant nullr nullC2/Nm2null, an average radius r nullmnull, and a density of electrical charge qr nullC/kgnull, and the image developed on the latent image retaining body by the first developing surface has an average thickness dr nullmnull at the second development station. The second liquid developer has an average thickness dt nullmnull at the second development station and a dielectric constant nullt nullC2/Nm2null, wherein following equations are satisfied, 1 1 null 10 - 11 null [ N ] null 4 null null null null null r 3 null null m null q r 3 null ( - q r null m r null r null d r null ( d r - 1 A null d r m r null ( - null null null null V q r + ( d r 2 null null r + d t null t ) null m r ) ) ) null 8 null 10 - 9 null [ N ] , and A = d p null p + d r null r + d t null t .
