摘要： In some embodiments, a drum unit may include an electrophotographic photosensitive member having a base member and a photosensitive layer on the base member. An embodiment may include a cleaning blade configured to abut the photosensitive layer to remove a developer remaining on the photosensitive layer of the electrophotographic photosensitive member. Some embodiments may include side seals disposed at both ends of the cleaning blade to inhibit leakage of the developer. In some embodiments, a portion of a side seal may be in contact with at least a portion of the surface and an end face of the photosensitive layer.

摘要： A photosensitive layer in a multilayer electrophotographic photoconductor includes a charge-generation layer including a charge-generating material having, as a major component, a titanyl phthalocyanine crystal which satisfies the conditions (A) and (B) below and a base resin, and a charge-transport layer including a charge-transporting material, the charge-generating material having, as a major component, the titanyl phthalocyanine crystal which has absorption at a wavelength of a charge-neutralizing light and which satisfies the conditions (A) and (B) or an X-form metal-free phthalocyanine crystal which has absorption at the wavelength of the charge-neutralizing light, and a binder resin. (A) In a Cu—Kα characteristic X-ray diffraction spectrum, one peak is present at a Bragg angle 2θ±0.2°=27.2°. (B) In a differential scanning calorimetry, one peak is present in a range of 270° C. to 400° C. except for peaks attributed to vaporization of adsorption water.
