An electrophotographic image forming apparatus for forming an image on a recording material includes a detachably-mounted cartridge including an electrophotographic photosensitive member, first and second portions-to-be-regulated for regulating rotation of the cartridge when a driving force receiving portion receives a driving force, and a transfer member for transferring a developer image formed on the electrophotographic photosensitive member onto a toner image receiving member. A supporting member is movable between an inside position which is in a main assembly of the apparatus and an outer portion, and a contacting and spacing member is movable relative to the supporting member. In addition, a first regulating portion permits movement of the supporting member between the outer position and the inside position, and a second regulating portion regulates rotation of the cartridge.

There is provided a display device including a display unit having pixels, each of which includes a luminescence element that individually becomes luminous depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a voltage signal, where the pixels are arranged in a matrix pattern. The display device includes an average luminance calculator (200) for calculating average luminance for a predetermined period of the input picture signal, and also includes a luminous time setter (202) for setting an effective duty depending on the calculated average luminance by the average luminance calculator (200), the effective duty regulating for each one frame a luminous time for which the luminescence element is luminous. The luminous time setter (202) sets the effective duty such that a luminescence amount regulated by a preset reference duty and possible maximum luminance of a picture signal.

A liquid crystal display includes: a light source section; a liquid crystal display panel including pixels each configured of sub-pixels of three colors red (R), green (G) and blue (B) and a sub-pixel of a color (Z) with higher luminance than the three colors; and a display control section including an output signal generation section performing a display drive on the sub-pixels of R, G, B and Z with use of the output picture signals. A chromaticity point of the emission light from the light source section is set to a position deviated from a white chromaticity point. In the case where the input picture signals are picture signals indicating white (W), the output signal generation section performs a chromaticity point adjustment to adjust, to the white chromaticity point, a chromaticity point of display light emitted from the liquid crystal display panel based on the emission light.
