Abstract

Developer cartridges (28) include a frame (34,35), developer carrying roller (31,65), and a driving force input gear (68). A first lengh distance between the axes of the gear and the developer carrying roller is about 14.0 mm. Another distance between the axis of the gear and the most distant surface of the developer carrying roller (65) is about 23.7 mm. Another developer cartridge includes between its side walls both a developer housing section with a height of about 45.8 mm and a developer supplying section (36) with a height of about 45 mm and for carrying developer froma the housing section to a photosensitive drum (92). Drum cartridges (27) include a rotatable photosensitive drum (92) extending between the side walls. A height distance between central portions of a ground electrode for grounding the drum and a transfer electrode for supplying voltage to a rotable transfer member (94) is about 17.9 mm. A width distance between side wall and tip of the extending drum shaft (125) is 7.6 mm. A process cartridge (20) includes in a length direction a developer housing section, developer supplying section (36) with a developer carrying roller (32) rotatable around a first axis (64), and a drum section (102) with a photosensitive drum (92) rotatable around a second axis (125). A length distance between the axes is 22 mm.
