A process cartridge detachably mountable to an image forming apparatus main body, said process cartridge comprising: an image bearing member; a charging member for charging the image bearing member; a developing member for developing an electrostatic latent image formed on the image bearing member; a first unit having the image bearing member and the charging member; a second unit swingably supported by said first unit and having said developing member; and a movable member (57, 58, 65) provided in said first unit so as to be movable between a first position and a second position with respect to said first unit and configured to move said charging member, wherein said charging member contacts said image bearing member when said movable member (57, 58, 65) is in said first position, wherein, when said movable member (57, 58, 65) is in said second position, a contact pressure of said charging member against said image bearing member is reduced in comparison with when said movable member (57, 58, 65) is in said first position or said charging member is separated from said image bearing member, wherein said second unit is configured to swing with respect to said first unit so that said second unit can assume a contacting position in which said second unit is configured to bring said developing member into contact with said image bearing member and a separating position in which said second unit is configured to separate said developing member from said image bearing member, wherein said second unit is configured to move from said contacting position to said separating position so that said second unit is brought into contact with said movable member (57, 58, 65) to move said movable member (57, 58, 65) from said first position to said second position, and wherein said second unit is configured to move from said separating position to said contacting position so as to permit said movable member (57, 58, 65) to move from said second position to said first position. an image bearing member; a charging member for charging the image bearing member; a developing member for developing an electrostatic latent image formed on the image bearing member; a first unit having the image bearing member and the charging member; a second unit swingably supported by said first unit and having said developing member; and a movable member (57, 58, 65) provided in said first unit so as to be movable between a first position and a second position with respect to said first unit and configured to move said charging member, wherein said charging member contacts said image bearing member when said movable member (57, 58, 65) is in said first position, wherein, when said movable member (57, 58, 65) is in said second position, a contact pressure of said charging member against said image bearing member is reduced in comparison with when said movable member (57, 58, 65) is in said first position or said charging member is separated from said image bearing member, wherein said second unit is configured to swing with respect to said first unit so that said second unit can assume a contacting position in which said second unit is configured to bring said developing member into contact with said image bearing member and a separating position in which said second unit is configured to separate said developing member from said image bearing member, wherein said second unit is configured to move from said contacting position to said separating position so that said second unit is brought into contact with said movable member (57, 58, 65) to move said movable member (57, 58, 65) from said first position to said second position, and wherein said second unit is configured to move from said separating position to said contacting position so as to permit said movable member (57, 58, 65) to move from said second position to said first position.
