Cartridge, process cartridge, and electrophotographic image forming apparatus

A process cartridge detachably mountable to a mounting portion provided in a main assembly of an electrophotographic image forming apparatus, said process cartridge comprising:

• an electrophotographic photosensitive member;
• a first frame rotatable supporting said electrophotographic photosensitive member;
• a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive member;
• a second frame rotatably supporting said developing roller;
• an electroconductive connection pin rotatably connecting said first frame and said second frame with each other, said electroconductive connection pin being electrically connectable to a main assembly electrical contact provided in the main assembly of the apparatus when said process cartridge is mounted to the mounting portion;
• a first portion to be guided and a second portion to be guided configured and positioned to be guided by a main assembly guide provided in the main assembly of the apparatus to guide said cartridge to the mounting portion when said process cartridge is mounted to the mounting portion;
• and
• a guide configured and positioned to guide the main assembly electrical contact to said connection pin so as to establish an electrical connection between the main assembly electrical contact and said connection pin when said cartridge is mounted to the mounting portion,
• wherein said guide is disposed between said first portion to be guided and said second portion to be guided, and said cartridge electrical contact is disposed upstream of said guide with respect to a direction in which said cartridge is mounted to the mounting portion.

An electrophotographic image forming apparatus for forming an image on a recording material, said electrophotographic image forming apparatus comprising:

• a mounting portion;
• a cartridge detachably mounted to said mounting portion, said electrophotographic image forming apparatus forming the image on the recording material using said cartridge;
• a main assembly electrical contact configured and positioned to electrically connect to a cartridge electrical contact provided in said cartridge when said cartridge is mounted to said mounting portion;
• and
• a main assembly guide configured and positioned to guide said cartridge to said mounting portion when said cartridge is mounted to said mounting portion;
• said cartridge including:
• process means for performing a process on an electrophotographic photosensitive member;
• a cartridge electrical contact configured and positioned to supply electric power to said process means, said cartridge electrical contact being electrically connectable to said main assembly electrical contact when said cartridge is mounted to said mounting portion;
• a first portion to be guided and a second portion to be guided configured and positioned to be guided by said main assembly guide to guide said cartridge to said mounting portion when said cartridge is mounted to said mounting portion;
• and
• a guide configured and positioned to guide said main assembly electrical contact to said cartridge electrical contact to establish an electrical connection between said main assembly electrical contact and said cartridge electrical contact when said cartridge is mounted to said mounting portion, wherein said guide and said cartridge electrical contact are is disposed between said first portion to be guided and said second portion to be guided, and said cartridge electrical contact is disposed upstream of said guide with respect to a direction in which said cartridge is mounted to said mounting portion.

A cartridge detachably mountable to a mounting portion provided in a main assembly of an electrophotographic image forming apparatus, said cartridge comprising:

• a cartridge electrical contact configured and positioned to supply electric power to process means actable on an electrophotographic photosensitive member from the main assembly of the apparatus, said cartridge electrical contact being electrically connectable to a main assembly electrical contact provided in the main assembly of the apparatus when said cartridge is mounted to the mounting portion;
• a first portion to be guided and a second portion to be guided configured and positioned to be guided by a main assembly guide provided in the main assembly of the apparatus to guide said cartridge to the mounting portion when said cartridge is mounted to the mounting portion;
• and
• a first guide and a second guide configured and positioned to guide the main assembly electrical contact to said cartridge electrical contact to establish an electrical connection between the main assembly electrical contact and said cartridge electrical contact when said cartridge is mounted to the mounting portion,
• wherein said first guide and second guide are disposed between said first portion to be guided and said second portion to be guided, and said cartridge electrical contact is disposed between said first guide and said second guide.
