A high reliability ceramic laminate suppresses delamination and cracks. Scrub mark images are captured, image data measured, and detailed information about the process is extracted through analysis. A brushless DC motor that includes a planetary gear set having an output shaft is disposed between the first and the second wiper assemblies. A wall is formed by the developer transported on the developer transport path, and the developer transported in a longitudinal direction is transported in the longitudinal direction while breaking a wall of the developer itself. In other words, the compound has an oxygen content lower than the stoichiometric oxygen content corresponding to a possible valence of the transition metal. The feedback cancellation system includes both a constrained adaptive filter, the constrained adaptive filter can be constrained by initiation coefficients, as well as an adaptive gain modification.
