An optical pickup and an optical disk apparatus of the invention includes a light sourcemounted with a light-emitting element constituted of a monoblock on a surface of a plateand emitting plural light beams, a light-receiving element, optical membersand a coupling basefor coupling the light source, the light-receiving elementand the optical members, wherein a light from the light sourceis directed through the optical memberstoward an optical disk, and a returning light from the optical disk is guided through the optical membersto the light-receiving element, characterized in that the plateprovided in the light sourceand the coupling baseare adjoined by a solder.

Optical pickup and optical disk apparatus

A color image-forming apparatus includes an endless belt-like photosensitive member stretched between and wound around a drive roller and a driven roller, and a plurality of developing rollers making contact with an outer surface of the photosensitive member. At least one flexure correction shaft is held in contact with an inner surface of the photosensitive member on the side remote from the developing rollers. With this construction, the condition of contact between each developing roller and the photosensitive member is made stable and uniform, and the developing conditions for all the colors become uniform so that a high-quality image can be obtained.
