A reliable surface-emitting type semiconductor laser and a method for manufacturing the same, is capable of controlling polarization planes of laser light without lowering the energy usage efficiency. The surface-emitting type semiconductor laser has a first mirror, an active layer and a second mirror formed above a substrate, a first columnar section formed adjacent to the active layer and including a dielectric layer defining an opening section and a second columnar section formed above the first columnar section. A planar configuration of the second columnar section has anisotropy.

An image forming apparatus transmits, when a function which cooperates with a function providing apparatus is added, information on the added function to a management server, and changes a failure monitoring setting according to the returned monitoring condition. If a failure occurs, the image forming apparatus generates, if the failure is attributable to the function providing apparatus, failure information indicating that the failure is attributable to the function providing apparatus, and otherwise, the image forming apparatus generates failure information on the failure to transmit to the management server. Upon receiving the information on the added function from the image forming apparatus, the management server returns the monitoring condition corresponding to the added function to arrange for maintenance of the image forming apparatus. If the failure is attributable to the function providing apparatus, the management server does not arrange for maintenance of the image forming apparatus.

A projector includes: a light emitter; a light modulator modulating light from the light emitter; and a projector projecting the image from the light modulator. The light emitter includes a light emitting element and an optical member. The light emitting element is a super luminescent diode having an active layer constituting first and second gain regions sandwiched between first and second cladding layers. The first gain region is tilted in a clockwise direction relative a perpendicular of a first surface of the stacked structure. The second gain region is tilted in a counterclockwise direction relative to a perpendicular of the first surface. As such, the optical member refracts the light respectively emitted from the end surfaces of the first and second gain regions on the second surface side to thereby emit light beams in the same direction.

A management server receives identification information including an IP address, MAC address, and product number of an image forming apparatus together with operation information thereof such as counter information via a network. Then, the management server determines whether the received identification information coincides with registration information. When the management server determines that the received identification information coincides with the registration information, the management server stores the operation information in association with a registered image forming apparatus.
