The developing portion includes a developing roller that develops an electrostatic latent image formed on an image-carrying member, and a driven-side shaft coupling that is provided on the developing roller.

Abstract: Separation of fat and water signals in MRI images can be achieved by a technique that includes using a spin-lock RF pulse sequence that incorporates adiabatic pulses and using Dixon methods for water/fat separation. The spin-lock RF pulse sequence can be, for example, an adiabatic continuous-wave constant-amplitude spin-lock (ACCSL) pulse sequence.

A spatial distribution of a spin-lock based imaging biomarker (e.g., T1rho) can be determined from the water image and/or the fat image.
